The Most Interesting Man in the World - S12-E17

The Most Interesting Man in the World - S12-E17
Continuity mistake: When Peter, Joe and Quagmire are watching Superman, they are first shown with three glasses on the table, one for each. After the scene of Superman is played on the TV, there are suddenly five glasses on the table. (00:03:30)
The Most Interesting Man in the World - S12-E17
Continuity mistake: At the Clam, when Peter mentions it was smart to wait out the thunderstorm, it is the middle of the day, but when Peter runs out of the Clam to go find Stewie, about 45 seconds later, it is suddenly sunset. (00:03:50 - 00:04:35)
Continuity mistake: When Joe, Peter, and Quagmire are sitting at the table in the bar, Joe takes off his sock and shoe to show them his foot. Cleveland comes in and Joe puts his leg back down and instantly has his sock and shoe back on.
Continuity mistake: Brian breaks his left leg at the race. Next scene the cast is on his right leg.
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.
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)
Stewie, Chris & Brian's Excellent Adventure - S13-E7
Factual error: The Titanic set sail from Southampton, not from London. (00:11:30)
Stewie, Chris & Brian's Excellent Adventure - S13-E7
Factual error: In the episode, the Titanic is shown to have sunk the same day it left England. The actual Titanic left England on April 10th and didn't sink until the night of April 14th, almost four days later. (00:11:40 - 00:15:30)
Stewie, Chris & Brian's Excellent Adventure - S13-E7

Stewie, Chris & Brian's Excellent Adventure - S13-E7
Plot hole: When it is revealed that Chris's teacher was never born, Teacher Doug introduces himself, despite the fact that if Chris's teacher was never born, Doug would already have been teacher for the entire year, and therefore all of the students should know him and he would not have to introduce himself.
Factual error: When Carter puts on the Jack LaLanne record, you can see it has eight individual grooves (or rings) around it. However, records only have one continuous groove.

Other mistake: After the airplane explodes, the group on the beach hold up their arms to shield themselves from falling debris. In a couple of frames, Cleveland's mustache loses its color and becomes like his flesh.
Continuity mistake: Peter, Quagmire, Cleveland and Joe are crawling through the air duct. Joes wheelchair is nowhere in sight yet when they fall to the floor it hits Joe in the head. (00:10:18)

Continuity mistake: In the principal's office, when everyone's talking about how Chris sent an inappropriate picture, Joe is there. After Joe says "This makes Chris a sex offender", he's got a relatively pointed nose. In the wide shot his nose is rounded.
The New Adventures of Old Tom - S14-E18
Continuity mistake: In the beginning of the episode the sign says "Every B deserves a J" underneath the sign of Jason's Jewelry but when Brian and Stewie go to return it that wording is gone.
The New Adventures of Old Tom - S14-E18
Continuity mistake: Peter goes to the roof where Tom is debating jumping. He has orange fingers because he ate a Doritos taco. He licks two fingers but next shot shows them all clean.
Continuity mistake: In the cutaway of Stewie talking with the three co-workers at the factory, there is a man towards the left of shot, leaning against a forklift. Beside the man is a female factory worker sitting on a crate about three to four feet to the left of him and her lunchbox is on the ground in front of the crate. In the next shot, as Stewie walks back to his forklift, the crate the woman is sitting on and the lunchbox are a much further distance from the man. The shot then pulls out, and the woman and her lunchbox are suddenly back to the original distance.
Continuity mistake: In the cutaway of Brian in the Old Yeller remake, he takes out a gun and goes to shoot a boy. When he first fires, the shell from the first gunshot lands on the ground beside him, but in the next shot, the shell has suddenly rotated itself by about 90° to the left.






Suggested correction: Quagmire considers the rest of them to be his best friends. He isn't drinking because they can't drink. He is complaining because since his friends can't drink - he won't drink, so he is still pissed.
It's still a plot hole considering Quagmire's age. I think the writers messed up big time.
You make a good point, but it's awkward to be that one person who is drinking while surrounded by people who can't. So, I understand the correction that was submitted above. Because his friends are not drinking, he now feels that he can't.
It's 100% a mistake. Quagmire simply would buy them alcohol the same way Brian did when they realized he could.
