The first is a bench clearly brawl started when 80K goes after Sherman Douglas.  He may be correct that he didn't land a punch, only because he was inept at fighting, but he got him into a good headlock and cleared the benches.

The next video shows him tripping on his own foot, blowing out his knee and everyone is outraged at Bill Lambier for pushing him (he was even touching him).
