He with out a doubt deserves an Emmy. Forget the fact that his character is by far the funniest on television, the ability to play the role is what makes him my number one choice for an award. The lines he has to remember are uncomparable to any other sitcom star I can remember. I don't even know what the hell he is saying half the time yet his delivery and facial expressions make me laugh my ass off.
I'm surprised he hasn't had any other major roles on tv but I'm sure Big Bang Theory won't be his last.
