Does anybody else find it odd the way Sheffield waves his bat back and forth while he's waiting for the pitch?

It looks like he's got the shakes from caffeine withdrawal or something. Oddly enough it doesn't effect his batting ability though. Good for Mets fans, bad for those of us cheering for the other guys.
Another batting oddity that miffs me is when the batter holds the bat up with one hand as if he's saying "I think I'll hit the ball over there!" I think Barry Bonds used to do that, which is why I don't like it much.
