That is weird as fuck. It is like a cyclops tooth!
I remember Mark and Brian giving him a bunch of shit about that tooth years ago. Dentists were calling into the show and offering to fix that anomaly for free, just for the exposure I suppose, but Tom Cruise really doesn't care. I guess it hasn't affected his career the least bit.
(BTW, Mark and Brian were extremely popular D.J.s in So Cal ~ even tried syndication for a while...95.5 KLOS) - I haven't checked the station in years. Don't even know if they are still around.
Kind of like Howard Stern. You can only take so much.
