I don't know what's funnier, that he threw the shoe or that he got his ass kicked for doing it.
Nick Diaz is likely done w/ the UFC. At least for a while. He had a rough falling out with UFC. Notice they didn't show his fight at the last UFC event; well that's b/c Diaz went behind their backs and signed a multi-fight deal w/ a diff/ organization before that fight. So the UFC's thought if Nick's not going to fight for us, we'd be stupid to keep building his fame by showing his fight, so they didn't televise it.
