Student Plays April Fools Prank on Teacher Who Insists She Answer Her Phone [VIDEO]

A professor who insists that students answer their ringing phones on speaker in his class got a lesson from a student on how to play the perfect April Fool's joke. I've seen a lot of videos like this, but this is the best, by far!

I understand the reason for the teacher's rule. He figures that if he forces the students to answer on speaker, they'll tell their friends not to call during his class. But, in this case, it backfired when students set up a phony call to play a prank.

Not only is the prank brilliant, but so is the way they let him know it's a joke. He takes it in stride and turns a lovely shade of red!
