South Park: Bigger, Longer & Uncut (1999)

Other mistake: When the switch is thrown to electrocute Terrence and Phillip, it's pulled downwards. A few shots later, we see Cartman jump in to save T and P by turning the switch off. He also pulls the switch downwards instead of pushing it upwards. (01:06:05)

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.

Trivia: In the scene at the United Nations, the US Ambassador claims that Terrance and Phillip will be put on trial for "corrupting America's youth" - a charge similar to that levied against Socrates. (00:24:40)
