The Mortal Instruments: City of Bones movie stills. I love this funny moment from the movie. Everything about it was great; the words, the tone, the facial expressions, and the characters involved. Conversation between Jace Wayland (played by Jamie Campbell Bower) and Simon Lewis (played by Robert Sheehan). Favorite moment is of course Jace's response, "I don't know why we haven't thought of that for the past 1000 years." His humor in this movie was perfect.
