This clip is so much better without any spoilers, so I’ll give you the bare minimum amount of context: the professor featured in the video has a strict policy that if a student’s cell phone rings during class, they have to answer it — on speaker phone.
One clever student used the rule to bring a hilarious amount of shame and embarrassment to the teacher in what might be 2014’s best April Fools’ prank this side of NPR’s Facebook page. Enjoy!
