Continuity: When Al is standing next to the juke box, Sam walks over to make a selection, and when Al starts talking his reflection is visible on the glass. Later in this episode, Sam is talking to Al at the sink of the dressing room at the ball park. As Sam looks into the mirror he says he thinks Al is a vampire, to which Al replies, "Neurological holograms don't reflect, Sam."

Continuity: The shaving cream smeared on Sam's face looks nothing at all like the cream on his reflection's (Tom's) face in the mirror.

Audio problem: During the speech where Al tells Sam to quit (to force Chewie to play), Sam says he can't quit but his mouth doesn't move for a couple seconds after the words start playing.

Factual error: The Post Raisin Bran cereal box sitting on the Beckett family breakfast table in 1969 has a 1990s box design.

Factual error: At the end, Sam reads a poem from a Mark Twain book and says, "Twain wrote it when his daughter died." But the poem, famous because it was engraved on the daughter's headstone, isn't by Twain, but by poet Robert Richardson. Twain never claimed authorship, so Sam couldn't be reading it with Twain's byline from any of his books.

Continuity: When Sam and his sister are on the trapeze and she does a double and he catches her you can see that the bar she jumped from is not moving behind her. Then when she jumps back to it, it's swinging again.

Continuity: As Sam is preparing to go on stage as Don Quixote, after catching the lead actor, a quick cut to Dulcinea dancing is shown. It is supposed to be Sam's love interest and ex piano teacher Nicole as Dulcinea. However, you can see Nicole standing in the background, in the pink outfit she was wearing in scenes from the beginning of the episode.

Factual error: In this episode that takes place in April of 1976, everyone sits around watching an episode of Saturday Night Live with Bill Murray on it. Murray didn't join the cast until 1977.
