Sherlock comes to the conclusion that Bob must be Cookie Monster, due to the cookies in the bag. Cookie Monster comes and eats the cookies from the bag, so Sherlock realizes that Bob can't be Cookie Monster. Bob then introduces himself, and Sherlock asks if Bob has cookies left that he may have. As Bob finds another cookie, Cookie Monster comes and takes it.
