Some of my favs are -
David Loueseau giving a spinning back kick to Rich Clementis midsection.
Yves Edwards amazing head kick to Josh Thompson (as he attempted a spinning backfist)
Rashad Evans KO of Sean Salmon
(Or course the Tim Sylvia KO of Tre Telligman ranks up there)
And of course Mirko 'Crocop' Filipovic back in his Pride days... Those were sick...
Ergo Bibo Sum - I drink, therefore I am.
Eggo Bibo Sum - I drink, therefore I waffle.
