Chocoholic ,
The best one I heard of was when a Saudi's son was selected to draw the winning ticket. When the kid put his hand into the barrel guess who had the winning ticket?? Apparently Daddy bought a raffle ticket, didn't deposit the stub into the barrel, but rather in his kid's hand, and the kid wound up pulling "the winning ticket", which happened to be in the possession of Daddy.

At the time people thought "what a coincidence" until the truth came out.
