Do not laugh when mourning me or I will come back to haunt you.

Alex Ludd says --
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
heart then closed, sealing the doctor in the beautiful heart forever.

At that point, one of the mourners burst into laughter. When all eyes stared
at him, he said, "I'm sorry, I was just thinking of my own funeral... I'm a
gynecologist."

That's when the proctologist chick fainted.
