The Moth and the Doctor A man walks into a doctor’s office. The doctor says, “Hello, what can I help you with today?” The man says, “Doctor, I think I’m a moth.” The doctor looks at him and says, “Oh, I’m not the right doctor for that. You should see a psychiatrist.” The man says, “I know, I know.” The doctor asks, “Then why did you come into my office?” The man says, “Because your light was on.”
