So what? It is friggin hilarious & I could not care less who said it first. Did you compete as a bodybuilder?
Arnold tried to deal with the Democrats--He bent over backwards for them to pass the budget and they shafted him. No wonder he's angry at this pack of rats. Maybe he's learning--you can't deal with em, you got to take em on in the court of public opinion. He's showing he can learn and hold them up for ridicule.
I think it's hilarious, too, and no, I have never competed as a bodybuilder. I got interested and lifted a lot of weight at one time. The original AP story ascribed the term to SNL; I just wanted to point out that that wasn't true.
