Pete Carroll is one sneaky snake. Watch this video to see his most recent practical joke on the USC football team. The sound quality is kind of poor, but during one of his meetings he tells his players that some of the players are being investigated for some internet piracy. Then, he informs then that they will go bowling instead of having practice. Good one Pete:) Source
Here's another video of Carrol doing an April Fools Day prank on Everson Griffen.
