When Sully places the menu on the table he puts it face down (logo first), then when he lifts up the table, to quickly get Boo, the menu is face up. See more...

Trivia

Towards the end, just after Mike yells "I'm on the cover of a magazine.", he waves the magazine around (it's "Business Shriek"). On the back cover of the magazine, there is an ad for a monster-styled Macintosh computer. The layout of the ad resembles the layout of Apple ads; the Apple logo, and a slogan "Scare Different" that resembles Apple's "Think Different", are blurred but still recognizable, at the bottom of the ad. This is visible for less than a second, and is best seen by single-stepping the frames on the DVD. Why Macintosh: Steven Jobs is the CEO of both Apple Computer and of Pixar, the company that animated Monsters Inc. See more...

When Mike, Sully, Boo, and Randal ride the doors out of the factory, it takes a couple of minutes for the ride to end. When the doors are called into the factory, however, it only takes about 10 seconds. [All of the monsters doing the scaring have doors assigned to them. Roz selects the doors for each monster and gives the door assignments to the monster's assistant. In order to expedite the scaring process the doors that are coming out to the scare floor would be placed closest to the storage exit, like a batter who is 'on deck'. When Mike, Sully, Boo and Randall ride the doors back all the way to their storage spots it is a much further trip.]

When Sully, Boo, and Mike are riding the door and Boo screams, only one door is activated. When she laughs in the same scene, every single door is activated. Near the end of the movie it is revealed that laughter is 10X more powerful than screams. In that case, only 10 doors should have been activated from her laugh. [Far too speculative. Clearly a child screaming must be able to power more than a single door, otherwise the activities at Monsters Inc. would be pointless, as it would take the same amount of power to collect a scream as that scream would later provide. There are far too many factors that go unaddressed in the film to make any definitive statement. For example, we know nothing about the comparable effective ranges of a scream and a laugh. From what we see in the film, a laugh can clearly provide power over a very large area, whereas a scream appears far more limited. It may simply be that the single door was the only one close enough to Boo to be powered by her scream, but when she laughed, there was enough power to fire up every door within range.]

Did you notice that Mike's mum looks like Roz? When they're doing the concert in the credits, after they do the play, Mike says, "What a night for my mother to be in the crowd", and you'll see Mike's mum. [This isn't trivia, it's just two characters with the same hairstyle.]
Edit
The monster that operates the doors for Randall, has legs that bend back like a bird's, but in the shot when Sulley saves Mike from the scream-extractor and puts that monster where Mike was, he is sitting down and his legs bend forward. [Fungus obviously has double-jointed legs, quite possible considering the diversity of monster oddities.]

One of my favorite parts in the movie: When you first see Roz, she is reading "The Glob." Look closely at the headlines - they are hilarious. For example, "Baby Born With Five Heads - Parents Thrilled". [How is this trivia? It's just a funny part of the movie.]

When Mike and Sulley are falling through the door vault, they escape through the door they are holding onto. When the door hits the ground, it completely shatters, including the metal frame that surrounds the door. No matter how hard that door hit the ground, the frame wouldn't have broken like wood. [You're assuming it's metal... clearly it wasn't. In any case, the laws of physics aren't the same in the monster world.]

Around the end of the movie, Sully has Boo activate all the doors so that they can get to Boo's door. However, having activated most doors around the world (some have been destroyed), there is no mention of anyone from the human world trying to access their closet, and coming upon the factory. We know that the doors work on both sides, as this is how Sully and co. get around from one location to the other. [We follow Sully, Mike, and Boo for the duration of the doors being active. Just because they didn't encounter anyone stumbling upon the factory does not mean no one did. We, the viewer, just didn't see it. If you opened up your closet and saw a huge open space on the other side that's never been there before are you likely to leave the door open for very long? I wouldn't.]

Near the end when Mike, Sully and Boo enter the factory on the back of door and the CDA's and Waternoose are waiting for them, Mike throws one of Boo's socks at a CDA, then runs off. When Sully and Boo come out from the behind the door Boo has both socks on. Later when Boo is returned to her room you can see the missing sock. [Look closer. The sock is gone the entire time, but the similarities between the color of the foot and the color of the sock make this hard to see.]
Edit Time
When Mike and Sulley are stuck in the Himalayas with the Yeti, the Yeti says that you can get milk from a Yak. This is not true as the Yak is the male of the species and the female (which would produce milk) is actually a Nak. [Character mistake. That's something most *people* don't know, so why would a monster from another world know that?]
Edit Corrected by Phixius
When Mike is in Harry Hausen's with Celia there is no menu on the table, then Sully appears and a menu is in front of them. [Sully brings the menu with him and slides it onto the table as he sits down. You can see it in his hand just before he reaches the table.]

Throughout the movie there are times when monsters prefer cleanliness and times when they prefer dirtiness. Examples of monsters preferring cleanliness include Sulley brushing his teeth at the beginning of the film (Mike says "Fight that plaque.") and a little later on at 'Monsters Inc' when a green slug monster mops the floor. Examples of monsters preferring dirtiness include Roz reading a newspaper with an article at the back of it that says 'Gain pounds' and when Mike asks Sulley for oderant (smelly garbage, old dumpster, low tide, wet dog). [What, monsters can't like smelliness but want their teeth not to fall out and their feet not to stick to the floor? Characters sometimes choosing convenience (chewing food, walking easily) over an aesthetic preference is not a plot hole. (And don't even get me started about calling weight gain "dirty.").]

When Mike tries to put the blame on Waxford he says that he works at station six. Waxford actually works on station nine which can be seen when they line themselves up the first day. [Mike could have messed up the stations in the heat of the lie.]
Edit
Taking into account Boo's height and the fact she can't talk very well puts her age at about 2. Her drawing ability however is that of a 5 or 6 year old. [Using someone's height and vocal abilities is not evidence to prove an age but pure assumption. Even if we could assume that was her age, its still presumptious to say what she could and couldn't do. As I mentioned we don't know how old she was and also have no idea of her abilities (i.e. Simple drawing). Besides which the drawing was not a professional looking painting but an simple crayon picture of the monsters, so its even more presumptious to those sort of drawings are a few years away.]
Edit Corrected by Lummie
In the opening scene, when the monster falls on the jacks, we see the door is less than half open. When the video is replayed, we see that the door is left more than half way open. [When the monster is on the ground spinning in circles, his feet hit the door closing it slightly.]

Mike uses a microphone to magnify his voice when doing his comedian bit with the kid at the end of the movie. You'd think the kid's parents would hear him. After all, near the end of the film Randall is teleported through a door to a trailer home, and the kid complains to his Maw that another 'gator has got in - and Maw not only sees and hears Randall, she belts him with a shovel - so she (or the shovel.) can feel him, too. [The microphone is probably just a prop for the comedian show, as you can't hear Mike's voice actually get louder (and with the echo microphones produce).]
Edit
In the computer animation process, they make certain set pieces which can be used over and over again - when mike is being threatened with the 'scream remover' you can see that it is made up of canisters for screams, and various other parts, including half a door sorting frame for the main arm [I don't think the convenience of repeating set pieces was a factor here: think of how many pieces needed to be made for the film. It makes more sense that Randall would build his secret machine out of parts available, such as the canisters and door frame. Still noteworthy however.]
Edit
When Mike and Sully are at the lockers and Mike puts in his contact, Randall slams Mike's locker, and that should have locked it, but Mike re-opens it with out re-entering the combination [Not all lockers immediately lock. In jr high school, our lockers could be shut without re-locking. You had to twist the dial as you left in order to lock the locker.]
Edit Time
When Sully and Mike first speak to the geeky monsters in the lobby, you can see a slug-like monster in the background just entering one of the corridors leading to the scarefloors. When Mike is talking to Celia a short time later, the same slug still has yet to enter the corridor. [They are similar, but, as stated elsewhere, there are certain common monster shapes that appear relatively frequently: slug-shape is one. Besides, the first slug has no lunchbox (judging from the movements of its right pseudopod) and the second one does.]

When Sully and Mike go back to work to take Boo back to her home, the clock on the wall as they enter says 8:50, a few minutes later Boo takes off and Mike and Sully go after her, a few minutes later Randell catches Mike and points to the clock which now reads 11:55. The chase only lasted a few minutes. [There are many clocks in the lobby of the power company, all over different hallways that lead to different scare floors and reading different times. This can be assumed to mean that the monsters recognize time zones (affirmed by the Eastern Seaboard lighting up during the first shift). The clock that reads 11:55 is "local time" for the monster world, but the other clocks refer to the human world.]

When Mike goes to get the card to Boo's door from Roz, there is a clipboard slightly to her right on the counter. The shot switches to Mike's view and when it switches back to Roz's view, the clipboard has moved to the right even though Roz is perfectly still. [Yes, the clipboard is now hidden behind Roz's head, but that is because the second shot is from closer to her shoulder. The clipboard is still the same distance from the loose papers on the desk.]
