Ranking the martial achievements of Matt Serra is likely a three way tie between: knocking GSP out to win the UFC title, eating a spinning backfist from Shonie Carter and whatever this video is.
Matt Serra knows many things, including pizza and pasta, but he also can choke you out anytime, any place because his jiu-jitsu game is that good. From what we assume is the UFC Unfiltered studios, we have Serra choking the hell out of NY comedian Ari Shaffir.
One day trained MMA fighters choking out untrained civilians will get old, today is not that day. Sorry Ari.
