There are certain things we all know about Michael Jackson. The moonwalk, for one. His large catalogue of very good songs, and then also Weird Al Yankovic's catalogue of very good Michael Jackson song parodies, for another. We know that he was friends, in a way, with Macaulay Culkin—etc., etc. But there is one thing I bet almost none of us know about Michael Jackson, and that is: he was perfect at prank phone calls.
