Recently if anyone saw Raul Marquez and Lorenzo...
Lorenzo was so frustrated late in the fight he really whacked him with his noggin hard! I believe it finally got a point taken away, and a crucial one at that. The judges had it a lot closer than I did. something like 114-113 x3. That butt lost Lorenzo his undefeated record.

Bika is a headbutting fool. He really was trying to mess up Calzaghe with that dome of his. not as blatant as Lorenzo's though.

Oh yeah.. and you can look at my icon up there (Rahman fyi). Yup good ol' Holyfield and his hard noggin at work.
