In tonight's episode of "America's Got Talent," Piers Morgan, Sharon Osbourne and Howie Mandel are treated to the death-defying antics of Professor Splash, a man who does a belly flop into a shallow inflatable pool from high above the audience.

Tension also seems to be rising backstage between judges Mandel and Morgan over Mandel's choices of contestants as well as practical jokes the judge has been playing on Morgan.
