So if you have not seen this already, take two minutes to witness one of the simplest, yet most cleverly executed pranks I've ever seen. For some background on the video, the teacher has a policy that every phone call must be answered and put on speakerphone. This girl's phone rings...
Luckily, the teacher is a good sport about it, claiming that he'll treasure the moment. The class bursts into laughter once the "mom" announces the child's name. April Fools.
