Continuity mistake: On the Conan O'Brien show, Terrance and Phillip put on moustaches, then Phillip farts in Terrance's face and Terrance goes flying off the screen with no moustache on.

Continuity mistake: The letters on Chef's apron change place and size between shots. (00:11:58)
Continuity mistake: When Stan looks down his road at the start of the movie you can see the Post Office, and there's nothing across the road but trees and snow. Later on, when he's in Tom's Rhinoplastry you can see the Post Office across the street. (01:00:00)
Continuity mistake: When the children and Christophe are on the hill near the military base, Christophe looks at his watch. It is a digital one then, but it's not when he says "Let's synchronize watches" a little bit later. (00:56:50 - 00:59:00)
Continuity mistake: When Terrance and Phillip are strapped in their chairs, the helmets on the chairs first appear in a closeup and aren't there in a previous wideshot. (00:55:00)

Continuity mistake: When looking across from Tom's Rhinoplastry you can see the Post Office, and when you look across from the cinema you can see Tom's Rhinoplastry. This would suggest that the Post Office and the cinema are right next to each other, but in any shots showing the front of the cinema, the Post Office is nowhere near it. (00:04:30)
Continuity mistake: In the long shot Stan is at the top of the steps singing 'there's a bunch' and you see him wobble down the steps, it then cuts to a close up and Stan is back at the top of the steps singing 'of birds in the sky' as he wobbles down the steps again. (00:00:30)

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.'"
