Hamlet is a pretty good straight man. He knows how to feed the clown his set-ups. I don’t think that is definitely what is going on here – but I do think that Hamlet has a comic sense and an ability to enjoy others’ comic sense and provide the necessary prompts to get the full effect of a joke. I mean, he does not have to ask “Why?” He could just let that statement roll on by but instead he asks and gets us all to the punchline.
