Poor and Stupid/Trivia

Trivia

 * After rehashing some of old South Park references in 200 and 201, Stone and Parker did this again by making Cartman exclaim "This is so tits!" when receiving the Vagisil NASCAR car. This goes back to the season four premiere, The Tooth Fairy Tats 2000, where Cartman uses 'tits' as an expression for 'cool' or 'awesome' whenever he gets money from the Tooth Fairy.
 * Stan and Kyle do not reappear after the first scene in this episode.
 * Cartman calls Butters by the nickname or petname 'B-Butts' for the first time in the series.
 * Memory loss is not a real side effect of Vagisil.
 * Matt and Trey tricked the viewers into that Kenny is going to be killed when two drivers, driving at full speed, notice Kenny is on the tracks right in front of them. Just at they are about to hit him however, they swerve out of the way, crashing into the sides (and probably dying themselves).

Goofs

 * Just moments after the doctor tells Cartman he has two fractured ribs, a broken femur, torn ligaments, two broken knees, and a level two concussion, Cartman walks out of his bed, and in the next scene, seems completely unharmed. However these injuries would make anyone immobile for a long period of time.
