Students Embarrass Their Professor In One Of The Best Pranks We've Ever Seen

A professor at Aquinas College in Grand Rapids, Michigan, has a policy that if a student's phone rings in class, they have to answer it on speakerphone - a pretty wily one, we think.

One student bravely put herself forward as the prankster, and what happened next leaves the macroeconomics professor feeling a little red-faced.
