Many people think Tom Cruise is full of hot air. After they watch this video, they'll realize that's not a figure of speech! From jumping on couches, to claiming to be the only person who could save someone in a car wreck, to maniacally laughing for no discernible reason, he's definitely a puzzle inside a riddle wrapped in an enigma. Well if anyone caught him on David Letterman a while back, they'll wonder what the eff was so funny. Some "fartist" (fart + artist) on YouTube has an answer. And if you know what's good for you, watch until the very end, when Oprah gets in on the fun. (FYI, I hate fart humor, usually, but when the normally lady-like Bella sent this my way, I had to share it. In short — blame her.)
