Heart specialist funeral

A famous heart specialist doctor died and everyone was gathered at his funeral. A regular coffin was displayed in front of a huge heart.

When the minister finished with the sermon and after everyone said their good-byes, 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 asked: "Why are you laughing?"

"I was thinking about my own funeral" the man replied.
"What's so funny about that?"

"I'm a gynecologist."
