Throwing It All Away - S10-E15
Factual error: In the opening scenes, Arizona mistakenly says a child suffering from eminent liver failure is at risk for psoriasis, when the script called for the word cirrhosis. Psoriasis is a skin disease. Cirrhosis is the medical term for end stage liver disease.

Thanksgiving - S1-E9
Factual error: The scene where Kitty is making peanut butter celery for Thanksgiving appetizers; she is using Skippy brand peanut butter and the packaging is not from the 70's, it's the current packaging. (00:05:10 - 00:06:05)

The One With The Hypnosis Tape - S3-E18
Factual error: When Pete takes Monica to Rome for the date this would have been impossible as Rome is 6 hours ahead of New York and at least 4/5 hours travel time, assuming they went by Concorde (double that otherwise). They would have had to have left New York early in the morning to make dinner for 8/9 pm in Rome.

Factual error: As the train is going backwards from the oncoming caboose, the camera pans to the field background and if you watch from right to left, you'll see a white vehicle driving in the background. (00:42:20)

The Beautiful Day in the Neighborhood - S5-E4
Factual error: Near the end, the gang is using Luminol to check for blood on neighbourhood signs. Luminol won't work in broad daylight, they should have used a blue light filtering lens to enhance its visibility.

How I Met Everyone Else - S3-E5
Factual error: When Ted is talking about what Marshall told him after he met Lilly, the two boys are playing with Playstation 2 controllers. The scene takes place in 1996, and Playstation 2 didn't come out until 2000.

Factual error: The verse Octavia recites is from Virgilius' poem "the Aeneid". That poem was written at least a quarter of a decade after the death of Caesar.

A Paige from the Past - S4-E10
Factual error: On the wall of Paige's bedroom when she was a teenager is a Metallica poster for "Garage Inc.", a CD not released until 1998 although Piper later says that Paige has gone back to 1994. (00:16:05)

Factual error: Samuel Clemens, who has written several humorous tales for the Territorial Enterprise, tells the publisher he would like to start writing serious news stories. The publisher replies, "This is a newspaper, not a comic strip. You write it and I'll print it." The first comic strip, "The Little Bears," debuted in 1893 and the term "comic strip" did not enter the vocabulary until 1920. "Bonanza" is set in the 1860s.

My motherboard, my self - S4-E8
Factual error: A motherboard crash would not result in Carrie's losing all of the files on her hard drive. The hard drive can be removed and placed into a peripheral, which can then be accessed by plugging it into a new computer.

Factual error: The show takes place in L.A, and in this episode (SPOILER ALERT) Tim and Jenny rush off to hastily and ill-advisedly get married. Los Angeles is three-four hours away from Vegas, where most quickie weddings are done, but a road sign shows them heading to Lake Tahoe/Reno, which is another four hours further away than that. It's just not plausible that they would skip Vegas, where everyone in Los Angeles goes for this purpose, to drive hours further along when they're in such a hurry. It does, however, make sense if you're either ignorant of California/Nevada geography, or if your show is filmed in woodsy British Columbia, where no location can be easily found that looks like the approach to Vegas. Also, the road sign reads, "Tahoe" - an obvious fake. Actual road signs read "Lake Tahoe" and they always show how many miles away it is.

Factual error: The communication delay for earth-moon communications is around 2.6 seconds. Yet Emma's daughter simply dials a cell phone and is connected to her Mom in space past the moon in less than that. The communication has no time lag. (00:18:45)

Factual error: When Dan goes into the machine for his MRI a light switches on just as his head enters the machine. MRIs have soft muted lights already in the machine (so technician can see the patient via cameras) they want you to rest and be calm to avoid claustrophobia, there are no bright lights. I have had 5 different MRIs in 4 different machines in 2 different states, all were the same. (00:02:00)

Factual error: When they first assault the city, the Greeks construct catapults. Only problem: catapults were invented at 400 - 300 BC, i.e. about 800 years later; and the first models looked similar to giant crossbows. The one-armed onager and similar types (as seen here) were a later Roman invention.

Episode #1.1 - S1-E1
Factual error: The American flag shown waving outside the White House is the current present-day flag with 50 stars. From 1896 to 1908, (the time period that this show is set in) the US flag only had 45 stars as Oklahoma, New Mexico, Nebraska, Alaska and Hawaii were not recognised as states in that time period. The flag did not have 50 stars until 1960. (00:04:30)

Factual error: During Lizzie's visit to Rosings Park, Lady Catherine presses her to stay longer, saying that if she will stay another month, she will be able to accommodate Lizzie "on the barouche-box" as far as London. This is nonsensical. What Austen actually wrote (Ch. 37) was: "And if you will stay another month complete, it will be in my power to take one of you as far as London, for I am going there early in June for a week; and as Dawson does not object to the barouche-box, there will be very good room for one of you. . ." The box is the coachman's seat on top of the carriage. Dawson is a servant, but if there were enough room inside the carriage, she would ride inside. What Lady Catherine is doing is offering Dawson's inside place to Lizzie. But in the movie, she is offering to let Lizzie ride outside next to the coachman. Not much of a treat.

Factual error: Willie opens the secret room in the Collins family mausoleum, and a flock of bats flies out. It's a hidden chamber that's been sealed (without even small openings - it's imprisoning a vampire) for 200 years. There'd be no way for the bats to get in. (00:15:00)

The Distance - S2-E1
Factual error: Julie picks up Marissa's iPod and presses the menu button, and Marissa acts as though the song has stopped, when pressing the menu button wouldn't do anything to the song - all that would do is have the playlist come up on the screen.

Water's Edge - S3-E3
Factual error: Pete Taylor's corpse is a bare skeleton after just two years in the sea-shack's attic, though it shouldn't be. There should at least be traces of hair and clothing surrounding the bones. (00:40:00)
