The Opium Den

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 fainted.
