A brain surgeon was holding a wedding reception at his home, when the night before the event, his hot water tank sprang a leak. He made a few desparate calls and finally found a plumber who arrived at at 11:15 that night, removed his old tank and installed a new one. When the plumber finished the job, he handed the surgeon his bill. "My God!" exclaimed the fellow, as he looked at the charge, "I don't make that kind of money and I'm a brain surgeon!" The plumber replied. "I didn't make that kind of money when I was a brain surgeon, either".
