Continuity: Lois and Meg take the red car for their vacation at the spa, but while they are gone, Peter is seen driving it a few times.

Audio problem: In the scene where Quagmire is bidding on the prostitutes panties, the auctioneer says that she had 9 STDs, but the closed captions have him saying, "She had 12 STDs."

Continuity: Pay attention to the items behind the police auctioneer. In the first couple of shots we see a statue of a knight on a horse to the left of the auctioneer. When the camera cuts to Peter, and then cuts back, the statue is gone. The statue is then back in the next shot.

Continuity: When Meg is waiting for Lois outside the hooters, she has a watch on her wrist. When she is talking with Lois, it just disappears after a couple of shots and we don't see it again.

Factual error: When Meg and Lois are in the back of a police car they escape by opening the backdoors and getting away. The reardoors of a policecar can only open from the outside, for obvious reasons and this escape could not be possible.
