If you’ve ever been a freshman in college, you understand how nerve-wracking the first day of class can be. This class got more than they bargained for when their “professor” informed them that over half of the students in his class fail and that med school hopefuls would probably never make the cut. The student impersonating the professor does a great job of the prank and has an air of authority, so the other students in the classroom fell for it beautifully.

The prank comes courtesy of the Chamber Boys, who have a radio show on the University of Rochester station.
