Growing up, making a prank call was as easy as picking up the rotary phone. Nowadays, telecommunication developments, like caller ID, have made the crank call nearly obsolete. While it may be more difficult to anonymously prank your principal, the tradition hasn't completely disappeared. Stand-up comic Jim Florentine, of Comedy Central's Crank Yankers, VH1's That Metal Show, and Howard Stern fame, discusses the inspiration behind his prank call series Terrorizing Telemarketers. Plus, he shares the story of one prank gone very, very wrong.
