Tom Cruise got into a water war with Jimmy Fallon when he dropped by Late Night in NYC yesterday. Tom, who appeared on the Late Show the previous night as part of his promotion for Jack Reacher, first sat down to chat with Jimmy about giving their mothers Christmas gifts. After Jimmy talked about how he once gave his mom a food processor from a local drugstore, he asked Tom if he ever gave his mom something nice "like that." Tom and the audience started to laugh, and he said, "Actually, I do think I got her a food processor. I remember, I wrapped it in a house." Later, Jimmy invited Tom to take part in their water war skit, where Jimmy and celebrities do battle by trying to drench each other with water. Tom won the water war and earned the privilege of spraying Jimmy with a powerful water cannon.
