I was thinking: wasn't it in the Pilot, when he is writing the story about the theater, before he is hired by Perry, that he has the pencil in his mouth? The screencaps don't show it (they don't show *every* instant of the episodes), but I have the impression that *that* was the scene you are looking for. He is wearing a blue shirt then. Can anybody else check in their own set of images or videos?
