Five doctors went to on a duck hunt: a GP, a pediatrician, a psychiatrist, a surgeon, and a pathologist.
After a while a bird came winging overhead, the GP raised his shogun but didn’t shoot because he wasn’t sure if it was a duck or not.
The pediatrician also raised his gun, but then he wasn’t sure if it was a male or female duck, so he didn’t shoot.
The psychiatrist raised his gun and then thought, I know that’s a duck, but does the duck know it’s a duck?”
The surgeon was the only one who shot. Boom!! He blew it away. Then he turned to the pathologist and said, “Go see if that was a duck.”
