Continuity mistake: In the first Andy and Lou sketch, when Andy sees the intro to 'The Price Is Right', there is a cup in front of him. However in the next shot Lou brings one over and it is the same one in the same position as in the first shot. Obviously the second shot was filmed first.
Continuity mistake: When Ryan is lighting Marissa's cigarette with his, at the start of the shot it's full, then the shot goes to Ryan and it's still full. But then the shot goes to Marissa and if you look at Ryan's cigarette you can see it is almost all gone. Then the shot goes to Ryan and the cigarette is full again. (00:09:00)
Continuity mistake: When Lindsay and Michael are talking about Maebe's grades, the test paper that Lindsay just put on the fridge door sits near a note about running out of milk. In the next shot, the items have moved and the test paper is now mostly covering the note.
Continuity mistake: When Rube's talking to the graffiti artist, he's painting what looks like a blue cat. We cut away, hear a brief paint spray, then cut back. There's now far more painted than that spray could have achieved, and what was there already has changed as well.
Continuity mistake: While Alan's sitting on the couch, Evelyn's talking to Alan "helping...through a very difficult time," and in the shots facing Alan all of the books on the table behind him, and also the books on the couch's side table keep changing - not just their position, all the books actually become different books. Additionally, in the shots facing Charlie, the books beside the chair and the books/CDs/DVDs on the bookcase change as well.
Beauty and the Obese: Part 1 - S1-E1
Continuity mistake: At the bar, a man slides up behind Persephone and asks how much for a lap dance. It cuts to a different angle as the bar tender comes up, and suddenly the bottles on the shelves behind the man have changed around. Most notably the orange bottle on the second shelf. (00:02:30)
