WWE Champion CM Punk, who trains Brazilian jiu-jitsu with Rener Gracie during his down time from pro wrestling, joins Gracie for a special edition of one of his "Gracie Breakdown" videos. In it, they travel back in time to cover the Royce Gracie vs. Dan Severn fight from UFC 4 way back on Dec. 16, 1994.
Gracie, of course, used a triangle choke to submit Severn, which Punk and Rener show you above. It's a cool video on its own but Punk's participation makes it a must watch for pro wrestling fans.
