Baby, You Knock Me Out - S9-E5

Factual error: When the guys enter the disco in the 1973 segment, "A Fifth of Beethoven" by Walter Murphy is heard playing; that song was recorded and released in 1976.
Big Man on Hippocampus - S8-E10
Factual error: Peter loses the last round on Family Feud. They got 199 points but needed 200 points to win $5000. Since they lost, they should've got $5 for every point which is $995. But they got nothing.
Baking Bad - S13-E3
Factual error: Everyone donating blood in this episode is being hooked up to bags already full of blood. Peter donates yet the bag he's hooked up to is already full. Really hazardous.
Factual error: When Peter is on The Price is Right, Drew says he's the top winner of the day so he'll spin first. However, the top winner always spins last.
Factual error: In the park, Stewie and Brian are playing the "water pipes" like a xylophone. Trouble is, in order to get the tones they were playing, the glasses should have had different levels of water in them. If you look closely, all the glasses have the same level of water.
'Family Guy' Through the Years - S16-E16
Factual error: In the scene at the Disco, Peter and Quagmire both transpose "Viet Cong" but with "Donkey Kong." However, the segment is supposed to be taking place in 1973, meanwhile "Donkey Kong" wasn't released until 1981.
Factual error: As soon as Lois and Peter board the ship it starts moving. This does not happen in reality.
Factual error: There's no way for the Griffins to climb clear to the top of Mt Everest. It takes months to prepare for that and oxygen tanks. This episode is one whole factual error. That and it costs 30 grand or more per person.

Factual error: A turkey does not burn and smoke 30 seconds after the oven timer goes off.
Factual error: Joe's plan to trick OJ into confessing to the 1994 murders is moot since, having been acquitted, the double jeopardy provision would prevent him from being tried for the same crime twice, and as a cop, Joe would know that.
Suggested correction: The plan to get OJ to confess had nothing to do with getting the confession, so he could be arrested or tried again. And at this point, the civil trial already found OJ "responsible" for the murders. Since OJ has always maintained his innocence, getting a confession on tape would just be big news.
Ocean's Three and a Half - S7-E7
Factual error: There's no way that Joe and Susie wear the same size diapers.
Stewie, Chris & Brian's Excellent Adventure - S13-E7
Factual error: They all go back to 1912 in London. When Stewie gives a street performer money, Brian informs him that the person wasn't Charlie Chaplin but in fact, Adolf Hitler, and he was right. Back in 1912, Hitler was living in Vienna, Austria and was poor after failing to get into art school. He didn't actually leave the country until 1913 when he moved to Munich, Germany. (00:10:20)
Factual error: You cannot get paternity test results back in one day. It takes 3 to 5 days or even weeks depending on the lab.
Factual error: When Peter is sent back to 1984, he plans to see Zapped! in the theater with Lois; Zapped! was released in 1982, and was no longer in theaters by 1984.
Factual error: While Trump is showing Peter around the White House, Trump stops and says, "Sorry, can you hang on a sec, gotta close this window, Melania's out there blowing bubbles for Eric." It's a fact that windows are not allowed to be opened in the White House for security sake. Michelle Obama was unaware at first and opened one and the secret service ordered her to shut that window immediately.
Factual error: Brian is sitting on the couch smoking weed. Joe knocks on the door and Brian just waves the smoke from the air. Joe is there to give Brian a drug test and says nothing about smelling weed in the air. There's no possible way he didn't smell it! You can't just wave your hand and get rid of the smell.
Factual error: When Lois, Meg, and Chris go to the stage show on the West End, "theater" is spelled with the Americanism "-er" instead of the UK spelling "-re."
