Where did you see Dave a couple of years ago? I am pretty sure he had a plug job. When you get to see a decent camera shot of his head, you can see the "plugs". More power to him, I say. He's definitely a freak. I'd give up my hair to look like that, too.
He was in the WWE like a year before he became part of Evolution. I think he used to always come out with Devon Dudley when he was doing that stint as a religious fanatic or whatever. His head was shaved bald and he used to wear big chain links around his neck
