Factual error: In the scene after Method Man cremates Ivory, the one where Method Man wakes up and goes to check on his plants, the weed on the Ivory plant is already trimmed, and dried. Method Man could've done this to the buds, but he reacts to it's potency like he has never seen it before.
Other mistake: When the guys find out that they've passed the THC test, Jamal turns to Silas and asks if they're still high on the ivory. At the moment he asks, an elf walks across the room. This is supposed to be a figment of their imagination as they are high, so why does the woman at the desk watch the elf too?
Factual error: One character says he is pledging a fraternity, but there are no fraternities at Harvard. They have Fox Clubs, as is correctly stated later in the film.
Continuity mistake: When Baby Powder smacks I Need Money, his visor falls off. In the next shot, when they are all falling out the door, the visor is back on his head.
Continuity mistake: When I Need Money is "stealing" Gerald's bike when he rolls it down the hill it has a black pocket thing of some sort attached to the frame but just before it hits the truck it disappears.
Continuity mistake: When Methodman and Jamal first meet in the car, the head on Methodman's toothbrush (in his hat) moves from towards his face to away from his face.
Continuity mistake: In the opening scene where Method Man has a naked woman sleeping in his bed, in one shot she has the covers pulled up covering her entire breast, in the next shot it is lower, and then higher.
