Mama said knock you out!
Self Proclaimed Tai Chi Master Calls It Quits 10 Seconds Into MMA Fighter Bout

Because life, sometimes in the form of a punch, comes at you quick, this is a video of MMA fighter Xu Xiaodong jabbing self-proclaimed defense training tai chi master Chen Yong in the face hard enough in the first ten seconds of their fight for Chen to tap out. Wow, so if this is master-level tai chi then a beginner really has a lot to look forward to in their development. I mean the way he couldn’t stop either one of those kicks or the punch — you don’t just learn that sort of technique overnight.

Keep going for the video, which should start playing at 27:14 when the fight is about to start, but skip there if it doesn’t.
