Continuity: In Stewie's first acting class, the chairs all the children are sitting on are blue but after Stewie has done his scene and he is talking to Olivia about her comment, the chairs are orange.

Continuity: When the Griffins are dining with the nudists, the leaves on the corn in the middle of the table change colour.

Continuity: When Simon is working with Stewie in his "The Life Cycle" exercise, there are three children behind him: a redhead with freckles, a blonde with glasses, and another blonde. However, after Simon turns around and says, "Any comments?", there is a wide pan of the kids in the class, and the three kids have completely disappeared.

Continuity: After the fight between Stewie and Olivia at the concert hall (followed by their breakup), Simon tells Stewie that the act without Olivia is "over" as he turns to walk off the screen. However, before Simon is even partially out of the shot, he completely disappears.

Continuity: When we first see Brian at the auditions, he is sitting between Stewie and an empty chair, but when he is called up, he is right next to the aisle.

Other: In this episode, Mort Goldman shows Peter a dating video he made, saying it's how he and his wife met. He is an adult in the video, yet in an earlier episode 'The Kiss Seen Round The World', Mort's wife tells the Griffins that she met him when they were just 14.

Continuity: When Peter goes to see his ex-girlfriend, she says she never washed her hand and takes off her right glove to show a black hand. It is like this right up until Peter leaves. She then turns around and the hands have switched colours.

Other: In the scene where Brian gets off the phone with the glue company, he says the bad news is that the substance to remove the glue takes two weeks to arrive, but the captions read seven days.

Revealing: When Brian and Stewie are on the tourbus, the scenery flashing past is just the same few buildings going by over and over.

Continuity: When Stewie is watching Jolly Farm Revue for the second time, he is sitting roughly in the centre of the mat, but in the next shot, he is sitting near the edge of it.

Continuity: After Peter says "Let him answer, Lois", he gets a lot closer to Dave between shots.

Continuity: When Brian says "You can't just ignore these years", the front cover of his magazine is different from how it was in previous shots.

Audio problem: When the English mother at the airport says "These are all ours", she says it in a posh American accent, not an English one.

Continuity: When we first see the English family at the airport, the girl in red is carrying a blue pack, but in the next shot, she is carrying a doll.

Factual error: When Peter has his KISS trivia game with Dave the nudist, he asks what the ad read that brought Peter Criss to KISS, and they both answer in unison: "Drummer willing to do anything to make it". In fact, the ad read: "Drummer with 15 years' experience willing to do anything to make it". As the original ad is referenced and shown in several biographies on KISS, as well as the "KISS: eXposed" video, it's not something these two trivia experts would have missed.

Other: The 'KISS' logo above Kiss's stage isn't actually held up by anything.

Continuity: During Kiss's performance, Paul Stanley (the one with the star face paint) and Ace Frehley (the one with the grey face paint), swap places multiple times.

Continuity: When Peter Criss jumps out from behind the drum-kit, the 'KISS' logo is at the top of the base drum. Then when he is singing the "Chattanooga Choo Choo" the 'KISS' logo is further down the drum.

Continuity: When Gene Simmons points the microphone at Lois, she is surrounded by people with Kiss make-up on. In the next shot, when she says "Is that it?", she is surrounded by a different group of people, one of whom is not wearing make-up.

Continuity: In the scene just before Lois doesn't know the lyrics to the song at the KISS concert, there is a multiple flashing of members of the band. In a shot of drummer Peter Criss, he has blond hair instead of his trademark black.
