Mike Tyson’s Fist Breaks Steve-O’s Nose At Charlie Sheen Roast [Video]

Mike Tyson did not plan on breaking Steve-O's nose at Charlie Sheen's roast, I'm guessing that he didn't even plan on touching Steve-O.

That did not stop the 'Jackass' star from running full speed at the former heavy weight champ, leading with his schnozz.

What happened next was as about as predictable as all of the jokes at the roast of Charlie Sheen.

Check out the highlights of the roast here, but trust me, you don't want to miss the outtake of the century below.
