CM Punk Punches Fan at WWE Monday Night Raw [VIDEO]

In the closing moments of Monday Night Raw last night, CM Punk ran into the audience to sneak away with his belt. What the TV cameras failed to pick up was him punching a fan.

What worse is that he punched the wrong fan.

As you can see, someone crept up behind him, pushed the back of his head and, CM Punk, in the heat of the moment, turned around and backhanded the guy who he thought was right behind him, knocking him down.

Here's a longer version of the video from some dude's phone.

Is this still right for him to do?
