Professor Stephen Barrows has a strict policy on cell phones in his macroeconomics class at Aquinas College in Grand Rapids, Mich. If your phone audibly rings in class, you have to answer it on speakerphone, sharing the call with the whole class.

Well, Barrows' students decided to turn the tables for April Fool's Day. See the epic joke that they call "BEST CLASSROOM APRIL FOOLS PRANK EVER" and how the pranked prof responded.
