Best Final Exam Panic Scenes

[Pale Rider]

Ok, what do you think are the best final exam panic scenes in a movie? You know, the kind of scene where a guy wakes up and realizes the final is half-over or has missed it altogether?

I remember one in Back to School with Rodney Dangerfield. My brother tells me there was one in Roadtrip with Tom Green, but I didn't see it.

Wasn't there one in some movie with Val Kilmer?
