A young doctor had just opened office and felt really excited. His secretary told him a man was here to see him. The young doctor told her to send him in.

Pretending to be a busy doctor, he picked up the phone just as the man came in. "Yes, that's right. The fee is $200. Yes, I'll expect you ten past two. Alright. No later. I'm a very busy man."

He hung up and turned to the man waiting. "May I help you?"

"No," said the man, "I just came in to install the phone."
