Beam Me Up, Scotty!: Done by Chip (and possibly the writers of the film too). He exclaims "Dry land is not a myth! I've seen it!" and then cites the quote as "Kevin Costner, Waterworld." Of course, this line is never actually spoken in Waterworld at any point, and Costner's character even says the exact opposite thing. Made even more grating because he immediately brags about having watched the movie several times.
I Knew It: Some of the Cable Guy's predictions about what cable will do for the future came true.
Playing Against Type: Averted. Carrey still uses the same rubbery-faced schtick in this movie that made him famous, only in the context of a manic Stalker Without A Crush rather than a living cartoon character like in Ace Ventura and The Mask, showing just how easily Carrey's signature style can be played up as creepy rather than funny.
Playing with Character Type: Carrey is just as zany and over-the-top as always, but it's done in part to demonstrate just how mentally disturbed Chip is rather than strictly for humour.
