I saw this movie fight last week that made my day

Yeah,I guess it was last week.
It was a comedy with a fantastic actor-Billy Crystal with an average-sometimes good actor Robin Williams (The name could have been "Fathers day" or something like that,if you´ve seen it,you know what I´m talking about)
At the beginning,Crystal fights a silly guy,he offers him a classic knee to groin,followed with a nice headbutt...
Yeah,he uses it a lot...at the later part of the movie Crystal and Robin do both headbutt a big audience/gang of rockers with their FOREheads,well it was a comedy but you just gotta love it...
"The power comes from the back"

Robin Williams headbutted a guy in "Good Morning Vietnam", too. He must have a hard head.

In "Exit Wounds", DMX headbutts Steven Seagal three times in the same fight scene.
