School for Scoundrels (2006)

Continuity mistake: When Roger is drunk and getting into bed, his alarm clock changes from 11:39 back to 11:38.

Dr. P: Every once in a while a shepherd has to pluck a sheep from the herd and challenge him. It lets the man know he's worthy of leading.
Roger: Well you know what? I don't want to be a shepherd anymore.
Dr. P: You're not the shepherd, dumb ass. I'm the shepherd. It's called an analogy, moron.
