Deliberate mistake: When Big Gay Al sings his song, he sits at the edge of the stage. In a wideshot the soldiers are just watching, yet in a closeup they're all waving lighters. (00:59:25)

South Park: Bigger, Longer & Uncut (1999)
1 deliberate mistake - chronological order
Directed by: Trey Parker
Starring: Trey Parker, Isaac Hayes, Matt Stone, Mary Kay Bergman
Continuity mistake: During the "La Resistance" number, during the verse, "They may stab you in the head, with a dagger or sword," We see a guy wearing blue with a blue hat on the left (probably Craig). In the next shot, he disappears, and in the next shot, he reappears. (00:50:05)
General: Now each battalion has a specific code-name and mission. Battalion 5, raise your hands!
[All of the African-Americans raise their hands.]
General: You will be the all important first defense wave, which we will call "Operation Human Shield."
Chef: Hey, wait a minute!
General: Now keep in mind, Operation Human Shield will suffer heavy losses. But don't lose your spirit, men! Stay until the bitter end. Battalion 14?
[The rest of the group, all Caucasian, raise their hands.]
General: Right, you are "Operation Get Behind The Darkies." You will follow Battalion 5 here, and try not to get killed for God's sake! Are there any questions, men?
[Chef raises his hand.]
General: Yes, soldier?
Chef: Haven't you heard of the Emancipation Proclamation?
General: I don't listen to hip-hop.
