Alternate ending where Sandler shoots everyone?
Once Sandler's character finds out that the whole anger management thing was just a trick, he snaps, grabs one of the cop's guns (at the stadium), and goes on a shooting spree, first shooting his girlfriend, and then Jack Nicholson's character.
Then he says, "I guess I am the cashier." and blows his brains out, then the ending credits start.
I have the Blu-ray but I can't find this ending. Is it an easter egg or something?
