A pipe burst in a doctor’s house. He called a plumber. The plumber arrived, unpacked his tools, did mysterious plumber-type things for a few minutes, and handed the doctor a bill for $600.
The doctor exclaimed, “This is ridiculous! I don’t even make that much as a doctor!”
The plumber grinned, “Neither did I when I was a doctor.”
If you want the world to beat a path to your door, just try to take a nap on a Saturday afternoon.
