Kelly makes it look easy. It’s not. You need a quick wit and be able to look at things in an interesting way. Being nice, good-looking, etc is not enough. When Kelly auditioned, I remember people saying she would be perfect, because she was the life of every party, always had people laughing, etc. Simon Helberg? (Howard, from Big Bang) would be perfect. In interviews he is hilarious and tells great stories off the cuff.
