My wife told me this the other day. She probably read it on sci.med, or something like that. Three doctors go on a hunting trip. They hear a rustling noise and look up to see some birds. The psychologist says, "Hmmm. Ducks. I wonder what it feels like to be a duck?" The internist says, "Probably ducks. Rule out geese, rule out pheasants." The surgeon doesn't say anything, he just takes his shotgun and blasts them all out of the sky. Then he hands one to the pathologist who always comes along with him and says, "Here, tell me what the hell this was?"
