I'll be the first to say I really like to see R-Truth in action. He's a great wrestler—not so great a rapper.
I mean, is he a rapper? I'm not clear. And if so, does he write any other songs? He's riding that one song more than Harvey Danger rode "Flagpole Sitta."
And why does he never enter through the backstage? Do they not let him back there? He's always walking through the audience rapping away, looking uncomfortable as hell as he's gotta rap, walk down stairs, and make sure some drunk 400 pound fan doesn't maul him in the process.
And that song is TERRIBLE. If you're trying to create a catchphrase why not go for something more original than "what's up"? I'm pretty sure its been done before.
Until something changes I'll continue to fast forward my DVR through his entrance until something less migraine-inducing comes out of his mouth.
