Continuity mistake: When Harold and Kumar pull up into the Burger Shack drive-through, the guy goes crazy, saying, "Let's burn this muthaf*cka down.", he then knocks over the rack in the back, and all the stuff falls off of it. A few shots later, the rack is upright again and all the stuff is back on the rack.
Continuity mistake: When Kumar is interviewing at Princeton, the cup is not only changing directions, but sometimes is missing and at one point it is sitting slanted on top of a pen.
Revealing mistake: As Harold and Kumar are driving through Newark they observe some guys beating up a 'lamer version of them'. Right after Harold and Kumar say "Holy Shit" we see the gang stop, pause and then start again. Watch the guy in the green beenie hat as he swings the baseball bat. He makes to hit the guy on the floor but actually stops the swing about three feet above him.

Revealing mistake: When Kumar is clipping his pubes in Harold's mirror, when they go to a close up of Kumar's face and torso when he's speaking, you can see the blue shorts he's wearing for the shot. When Harold entered the room we can see Kumar from behind nude facing the mirror.
Factual error: They said that they were going to a White Castle in Cherry Hill, NJ. In reality, at the time, the White Castle was located in Pennsauken, NJ (about 10 minutes from Cherry Hill). Also, there are no cliffs anywhere near that location. The area is pretty flat.

Continuity mistake: When Kumar gets out of the car to go pee, Harold pulls out his laptop. As he is leaning forward to pick it up, he is not wearing his glasses. He picks up the laptop with both hands and starts to open it, never having his hands have time to put on glasses but suddenly he has glasses on.
