Weekend in Bangkok with Two Olympic Gymnasts - S3-E1
Revealing mistake: When Alan falls off the ladder you can see the ladder has been set up so it will fall back safely. As the ladder goes back towards the balcony rail, it hits the railing and bounces up. The bottom of the ladder, which is unseen, seems to be planted as it does not move during this. When Alan was climbing up and down the ladder, it wasn't secured with anything at the bottom. Thus the reason for him falling off the ladder. (00:03:35)
Anteaters. They're Just Crazy-lookin - S4-E23
Audio problem: In the episode with Enrique Iglesias, Charlie comes out to the deck to get his girlfriend and asks, "Isn't there something you could sand?" His lips say, "Isn't there something you could saw?"
Continuity mistake: Right on 21 minutes into the episode, when Charlie and Jake are in the car, Alan comes in with food and coffee, but doesn't close the car door. After he's handed Charlie the food and coffee, they change camera angle and you can see the door is closed. (00:19:55)
Just Once With Aunt Sophie - S3-E22
Continuity mistake: Alan says he hasn't been able to eat bananas since he was in high school. But in season 2 he does eat a banana more than once.
Factual error: Walden's Skype rings as if it was Bridget who called him, but it is obviously the other way around.
Can You Eat Human Flesh With Wooden Teeth? - S2-E16
Revealing mistake: When driving back after leaving Jake in the rain, the rain that settles on the bonnet of the car starts to pool. On a moving car this doesn't happen. Therefore you can tell the car wasn't moving. (00:09:20)
Your Dismissive Attitude Toward Boobs - S3-E4
Continuity mistake: When Charlie, Alan and Jake are arguing about Alan having overstayed his welcome, Jake's hands constantly change place. (00:09:45)
Camel Filters + Pheromones - S1-E12
Continuity mistake: In the scene where Charlie and Prudence are talking about Berta, the amount of soap on Prudence's stomach changes throughout.
Dum Diddy Dum Diddy Doo - S5-E3
Other mistake: When Jake is sitting on the couch talking on the phone, he says out loud "we were on a train in a tunnel?" etc, Alan has not walked into the house yet, therefore could not hear Jake's phone conversation. However when Jake walks past Alan and continues talking on phone, Alan states "at least he isn't the tunnel." Alan was not inside at the time of this conversation, so it makes no sense that he would have heard Jake say this.
Your Dismissive Attitude Toward Boobs - S3-E4
Continuity mistake: When Charlie opens the refrigerator when talking to Alan, he is holding a cup and the position he is holding it changes from when he opens and shuts the refrigerator door.
Santa's Village of the Damned - S3-E11
Continuity mistake: When Jake and Alan are in the car, They are talking about having Chinese food for Christmas dinner. When doing so, the car behind them changes from a black 4x4 to a red sports car. Then back. There is not enough time between shots for the cars to maneuver.
Does This Smell Funny to You? - S2-E24
Revealing mistake: At the start, Jake is writing the end of his report in class. However, watch closely and his pencil isn't on the paper. (00:00:25)
Revealing mistake: Most of the time, whenever the characters have a hot drink there is nothing in the cup.
Revealing mistake: When Charlie and Jake are at the supermarket Jake tells his uncle to switch milk brands, and when Charlie puts the Dairy Farm 1/2 gallon milk carton back on the shelf it wobbles easily back and forth, revealing it's actually an empty carton.
Hookers, Hookers, Hookers - S8-E4
Character mistake: Gordon says that he never had sex with anyone Alan knows, yet in Season 3 he briefly dated Rose and according to Rose also had sex with her.
Round One to the Hot Crazy Chick (1) - S1-E15
Factual error: When Frankie throws her pills out of the car, she reaches into the center console to open the window. The Jaguar Charlie is driving has its power windows in the door, a place she couldn't reach from her position.
Enjoy Those Garlic Balls - S2-E2
Continuity mistake: The level of tequila in the bottle at the start changes instantly depending on the angle. (00:01:35)
Character mistake: Jake's claim that a vomitorium was place for Romans to vomit is wrong and a common misconception. A vomitorium in reality is a passage in a stadium where a large number of people can exit at once.
Skunk, Dog Crap and Ketchup - S8-E13
Factual error: Despite Alan's general bad luck he indeed wouldn't have to be afraid of the skunks. In reality skunks use their anal scent glands very reluctantly and only if they feel threatened because they only carry a limited amount of liquid and have a rather long "recharging" time. To that effect a skunk that apparently feels home in a suburban surrounding would never feel threatened by a human.
Love Isn't Blind, It's Retarded - S3-E14
Continuity mistake: Near the end, when Kandi is saying that Aland sounds like a loser, her hand is by her head. Camera cuts and it's now in her lap.
Chosen answer: Alan might have thought the bra was too fancy to belong to a regular woman, "I'd love to meet the girl who filled this", he says. He assumed it was one of Charlie's many women.
