Some guy pretended to be a lecturer on the first day of uni.

How do you make a lecture hall of first year university students collectively crap themselves?

Why, playing one of the best pranks of all time on them, of course. Comedy group, The Chamber Boys at The University of Rochester decided to dress up as Dr. Hefensteiner – a fictional Professor from hell. He doesn’t so much as yell or scream at them, rather tell them that their chances of entering medical school are slim and there is a 55% failure rate.

The real Professor was in on the joke the whole time which makes him a little bit mean as well…
