The Funeral

A heart specialist doctor died and they're having his funeral. The coffin was placed in front of a huge heart. When the priest finished with the
sermon and after everyone said their good-byes, the heart opened, the coffin rolled inside, then 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."

What if he was a proctologist?
