- One of the channels Sharon flips through is showing a Cheesy Poofs commercial.
- Cartman had previously exacted revenge on the parents of Craig, Clyde, and Kyle.
- Cartman's more extreme revenge package, "We'll lure your parents out of the house, and then we'll kill them. Uh, we'll cut them up into little pieces and feed them to the dog", is very similar to his final revenge on Scott Tenorman in “Scott Tenorman Must Die”.
- After Butters' parents find out what he did, instead of grounding him, they apologize for lying to him, which is surprising given that they have grounded him for doing almost nothing in the past.

- At one point, Stan briefly watches The Osbournes before his mother changes the channel on him, telling him that the show will make him "retarded". To poke fun at the frequent cursing in The Osbournes, random pieces of dialogue were censored, even if the family wasn't actually swearing at the time.
- The song “My Future Self n' Me” is a parody of the theme song of the 1980s situation comedy Silver Spoons.

- Theoretically, if Cartman became a mechanic, he would never have actually had the chance to go back in time and tell himself about his future as a time travel CEO, because he didn't invent it. This is a form of 'grandfather paradox,' in which it is impossible for one to change the past because it would alter one's present.
