Fight: Vitali Klitschko vs. Lennox Lewis

Apparently homie didn't feel it because he was pissed when the fight was stopped in the sixth round and he lost his WBC and IBO heavyweight titles. To watch Lewis clown Klitschko and see exactly how out of it Vitali was, check this clip from the hilarious post-fight interviews.
