When Taj is getting ready to give Naomi a massage, she tells him she likes the song on the stereo. Taj replies "It is the White Barry" (meaning Barry White). It's actually a song called "Stumblin' In" performed by Suzie Quatro and Chris Norman.
Burned money is still legal tender as long as 51% is identifiable. the US treasury has a department that investigates damaged money and will issue replacements for the damaged money. Van shouldn't have to worry about needing more money.
At the beginning of the movie there is a kid about to jump to his death at the top of one of the campus buildings. When Van approaches him to talk him down he has his hands crossed behind his back. In the next shot they are on his hips (apparently so that we can see that he has no pants on). One shot later, from the front view, his hands are folded behind his back again.
When Van's father arrives at the party at the end of the movie to congratulate his son, he says that Gwen sent him a copy of the article, and he holds up a copy of The Liberator. But earlier in the film, we see Gwen send him a hand-typed copy since the paper wouldn't have gone to press yet.
During Van's halftime speech, he says how he is going to invite girls from Mount Holyoke in Massachusetts, yet the logo on the basketball court is for the Big Sky, a conference in the Northwestern United States
When Gwen calls Van toward the end of the movie and he unplugs the phone, you hear a dial tone on her end of the phone. If you unplug a phone, the person on the other end will just hear it continue to ring. It would not disconnect the call.
