Trying to make his students turn off their cellphones during class, this teacher has instituted a class policy saying says that if a student’s phone rings during class, then that student has to answer it on speaker so that everybody else in class can hear the conversation. It all backfired when a few of his students decided to play him a prank on April Fool’s Day.

I’m not going to say what the prank was cause I don’t want to ruin the surprise, but let’s just say that by the end of it the teacher was so embarrassed that is entire face was red.
