A doctor comes home and finds he has no water so he calls a plumber. The plumber walks in and has the water back on in 5 minutes. The plumber turns around and hands the doctor a bill for $275.00. The outraged doctor stammers, "I'm a neurosurgeon, not some lowly plumber, and I don't even make that much for 5 minutes work!" The plumber smiles and says "Yeah, I know, I didn't make that much when I was a neurosurgeon either"
