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 beautiful heart then closed, sealing the doctor inside for eternity.
At that point, one of the mourners burst into laughter. When everyone turned and stared at him, he apologized "I am sorry, I was just thinking of my own funeral... I am a gynecologist!"
At that point, the proctologist sitting next to him fainted.
