Factual error: In the song "It's Easy, mmmkay", Mr. Macky tells the children "With bitch drop the t 'cause 'bich' is Latin for generosity". Actually, there's no such word as 'bich' in the Latin language (the most common translation of generosity is 'magnanimitas').

Answer: Some versions of the film (VHS in Australia for one) contain the reference to the letter. Terrance: "Well, f*** my a** and call me a b**ch. I just got a letter." Phillip: "A letter from who, you sh**-sucking co**master?" Terrance: "It's from your mother." Phillip: "My mother sent YOU a letter? What's it say?" "Terrance: It says, 'Dear Terrance, please don't ever tell my son that I licked your hairy b***s.'"
