A cardiologist died and was given an elaborate funeral.  A huge HEART covered in flowers stood behind the casket during the service.  Following the eulogy, the heart opened, and the casket rolled inside.  The heart then closed, sealing the doctor in the beautiful heart forever.

At that point, one of the mourners burst into laughter.  When all eyes stared at him he said, "I'm sorry, I was just thinking of my own funeral - I'm a gynecologist."

The proctologist fainted.
