Sister Margaret died and through some error found herself in hell. 
She immediately called Saint Peter and said, 

"This is Sister Margaret. There's been a terrible mistake!" 

She explained the situation, and Saint Peter said he'd get right on
it. The next day the nun didn't hear from Saint Peter so she called him 
again. "Please set this error straight before tomorrow," she begged. 

"There's an orgy planned for tonight, and everyone *must* attend!" 

"Of course, Sister," he said. "I'll get you out of there right away." 

Apparently, her plight slipped his mind, and the following morning 
Saint Peter received another phone call from hell. He picked up 
the receiver with tribulations of his heart and started to listen.

He heard the following, "Hey, Pete, this is Maggie. Never mind!"
