A famous heart surgeon died and everyone was gathered at his funeral. A coffin was displayed in front of a huge heart. When the minister finished with the sermon and after everyone had paid their respects, the heart was opened, the coffin rolled inside, and the heart closed.

Just at that moment one of the mourners started laughing. The guy next to him said, control yourself man.

I'm sorry, he replied, I was thinking about my own funeral.

What's so funny about that?

I'm a gynecologist.
