Simon: (on playing his character on "The Big Bang Theory") It's appealing to play somebody who is so confident in every possible way. For me, believe it or not, it's a stretch. It may not be a huge stretch for me to play a nerd, but to play a super confident guy is a bit different. I tend to be a little more indecisive and insecure about things. It's pretty fun to get to just be out there and so smug and all knowing about all the situations that he's been in with a woman.
