As they say, there are two rules in improv: Never say no, and never ask why. When another actor asks 'Why?' or says no to something you're suggesting, then it's very clear that they're putting the onus on you, because they're not comfortable with it themselves.

Entourage' is a great show, but it's fantasy. I spent my twenties in L.A. in this business, and my life didn't look anything like that. 'Big Bang' reflects a side of men that is rarely shown. We see their flaws - all of them.

Just selfishly, I wanted to be associated with something as synonymous with cool and cutting edge and artistic as CBGB. People are aware of that, at least, even if nothing else. That's something to be proud of, to be a small part of the association with something like that.

It's that one thing that you're passionate about, that you end up developing tunnel vision for and everything else tends to fall by the wayside. Passion is appealing and universal.

It's never been a priority for me to concentrate on the likability of the character.

There is that stereotype of a nerd with the high pants and pocket protector and that kind of thing. That can sustain comedy for maybe a movie - hence the 'Revenge of the Nerds' franchise - but not for hopefully years on the air. It's a sight gag, not a story.
