Tom Cruise is a very serious man. He laughs, but it is a controlled laughter. Yesterday, when he was on The Tonight Show, he could not control himself. Could be because Jimmy Fallon asked him to star in Mad Lib Theater with him and the two of them acted out the silliest scene. It is hard to keep a straight face when you are saying such goofy things.
The goofier, the better for us. It was nice to see Cruise have some fun and let loose. He should do it more often. It would make him more likable and approachable.
