I stole mine from a song on the Bob & Tom morning radio show in which they use a bunch of names that you can use to trick someone on a prank call such as Mike Hunt, Harry Ballsack, Dick Fitzwell, etc.... When I was playing online poker a few years ago, I was looking for a name that would give me a loose table image so people would make a wrong assumption right off the bat. Also, Stew Pidaso is one of those prank names that is not so obvious, so it is easier to fool someone and they usually get more of a kick out of it once they get it.
