April Fool's Day may be long over, but a good prank is fun to watch no matter what day it is.

This instantly classic joke takes place in a classroom at Aquinas College. The professor has a policy that if a student's phone rings in class, he or she must put it on speaker so everyone can hear. That becomes a questionable rule after one student gets a call from a pregnancy clinic.

Let's give credit to the professor -- even though he's the butt of the joke, he certainly took it in stride.
