"Plumber vs Surgeon" joke

It was Sunday, when the brain surgeon discovered a huge leak in his basement pipe. He rushed upstairs and called the plumber.

"Triple-A Plumbing? This is an emergency! Get over here quick!"

"Okay, but I charge extra for Sunday emergency service," replied the plumber.

"Anything! Just stop this leak!"

The plumber arrived, took out a tiny wrench from his bag, and lightly tapped the pipe. The leak stopped. The plumber handed the relieved homeowner a bill for $500.00.

"What?" screamed the surgeon. "That's unbelievable! Why, I'm a brain surgeon and I don't make $500 for 5 minutes' work!"

"I know," agreed the plumber. "Neither did I when I was a brain surgeon!"
