Other mistake: When the boys cause a mini tremor by blowing up the girls' base, the time at which it occurs is strange because when they do it, both Stan's parents are at home (even though they both have jobs), Ms. Choksondik and Mr. Mackey are at Choksondik's house getting it on (indicating that school is over) and the other teachers are still at the school.
Other mistake: In "Broadway Bro Down," when Shelly and Larry are playing Settlers of Catan, Shelly tells him, "And I got a victory point for the most roads connecting settlements." In the game, there's a two victory point bonus for the longest road, but no points for getting the most roads. (00:14:10)Captain Defenestrator
Other mistake: Cartman says, "What? What happened you guys? Is Kenny okay?" The bandages only covered his eyes, not his ears, so even if he's blinded by his bandages, he still should have been able to hear Stan shouting, "Oh my God! She killed Kenny!" and Kyle's reply "You bastard!"Shay
Other mistake: When the guys play Lady Gaga's "Poker Face" on Rock Band 2, there are a few problems. The TV screen shows 4 people playing (the guitar, bass, drums, and vocals) when actually 3 people are playing, the TV repeats itself on a constant loop, and there are no lyrics on the screen shown. Also the drums go from right to left: blue, yellow, red, and green. The drums are supposed to go red, yellow, blue, and green.
