How this man pulls off skinny jeans and turtlenecks, I can't figure out. But what I can figure out is his humor. As creepy as his character may seem on the Big Bang Theory, Simon succeeds in portraying the character in a fun and oddly charming way. But BBT fans aren't the only ones who can appreciate him. Simon had a small but memorable part in Joss Whedon's "Dr. Horrible," and he never failed to make me laugh when watching "A Cinderella Story" years ago (though at the time I had no idea who he was). Overall, many of his parts have been secondary, but still, he hasn't been getting as much attention as he deserves!
