Jimmy Kimmel is one cruel dude. But with that being said, I have to admit that his cruelty is quite entertaining.

For his latest prank, Kimmel got together with one of his writers to scare the living hell out of his roommate, who just so happens to believe in ghosts. They terrorized the poor guy with all kinds of random, spooky noises until ultimately filling the room with smoke right before the writer busts in and lets his roommate in on the prank.
