doctor's funeral

A cardiac specialist died and at his funeral the coffin was placed infront of a huge mock up of a heart made up of flowers.  When the pastorfinished with the sermon and eulogy, and aftereveryone said theirgood-byes, the heart opened, the coffin rolled inside and the heartclosed. Just then one of the mourners burst into laughter.The guy next to him asked: "Why are you laughing?""I was thinking about my own funeral" the manreplied."What's so funny about that?""I'm a gynecologist."
