You may remember Glenn Hughes from the 2004 World Series of Poker asking--no, DEMANDING--in a very loud voice for the dealer to give him a tournament-saving card. It worked at least one time that I recall, and Hughes made the final table that year, finishing 5th.
A big crowd just gathered around Hughes' table as he was all-in against Leandro Pimentel. Hughes had to Pimentel's . "That ain't nothin'!" Hughes said. "Put a Jack up there!" And, lo and behold, the dealer put the on the board! Thing is, Hughes didn't tell the dealer not to put the out there on the river. Which is exactly what happened. And that spelled the end of Hughes' day.
