No, the lamest finishing move ever would be the People's Elbow. It's a fucking running elbow drop! What is so devastating about a move that is just an elbow drop after a guy has run the ropes? The Worm was just as bad, but Rock won championships, WWF championships, with the People's Elbow.
As far as Punk's heel turn goes: awesome! The ending of Raw was perfect. It was exactly what they needed to do to hopefully pull in the fans that watched tonight because of nostalgia. Those people just saw one of their guys (The Rock) get taken out by one of these new guys (Punk) and that might get them to tune in next week. Great cliff hanger.
I also wonder if this means Summerslam's main event will be Punk vs. Rock. I know that Rock said he's fighting for the title at the Rumble, but the way Raw ended, maybe he comes back next week and says, "Screw the Rumble! I want my title match in LA... at Summerslam!" But maybe we'll just get a three-way with Punk, Show and Cena. I don't know, and that's what is great about how the show ended; a lot of ambiguity as to what will happen next.
But one thing we do know is we will see, at some point, a Punk-Rock match; after the way Raw ended tonight, I think that is ahon-sized guaran-damn-tee.
