C.M. Punk is one of the best things going in professional wrestling today. He's held numerious titles including the Ring Of Honor world heavyweight championship that he beat Austin Aries for. His series of matches with Samoa Joe for the ROH world title are legendary in the same way people look at Flair-Steamboat.
C.M. Punk's going to be a future world champion in World Wrestling Entertainment.
However I don't see Triple H taking too kindly to the Pepsi Plunge. We'll just have to settle for the Anaconda Vice, not that it isn't a great submission finish. In fact, its currently the best submission finish this side of the Crippler Crossface or the Koji Clutch.
Edit: And no, C.M. Punk has absolutely no relation to Shannon "The Prince Of Punk" Moore. C.M. Punk can wrestle rings around Shannon Moore.
