Unlike Jack Bauer, Kiefer Sutherland doesn't throw any punches. Literally.

According to The Hollywood Reporter, Sutherland was in attendance at an NYC club this past Monday night when fashion designer Jack McCollough "rudely bumped" into actress Brooke Shields while she was speaking with Sutherland. After McCollough refused to apologize - wait for it - Sutherland headbutted him!

Normally, this wouldn't be that big a deal. Celebrity makes a boo-boo, money exchanges hands out of court, problem solved. However, fans of 24 may recall that during production of the FOX drama's seventh season, Sutherland was busted for drunk driving. He served 48 days in jail but it never interfered with production because the writer's strike halted it.

I don't really follow sports, and I definitely don't keep track of what's going on as far as the World Cup is concerned, but a couple blogs are mentioning a recent scuffle between Zinedine Zidane and Marco Materazzi that culminated in Zidane headbutting Materazzi and sending him flailing to the ground. If you look at the lovely GIF of the incident, it looks as if Materazzi is actually being headbutted in the chin and neck, which means Zidane's aim isn't very good. Speculation is abound over just what set Zidane off, but apparently it had something to do with a racist comment that was made by Materazzi. All I know is that I've never understood headbutting as a form of fighting, as it would seem to do just as much damage to you as your opponent. This is why soccer players should carry knives ... wait, no.
