I don't know. Internet hype aside Chuck Norris really has no Charisma. He's as dull as a board of wood.
It'd probably just be something like
"Hi, i'm Chuck Norris" Followed by a WOW animation of him spinkicking the crap out of stuff.
I think they'd make him say a Chuck Norris jokes and then one involving WoW. I mean that's what I would hope for at least.
