Jerry was removing some engine valves from a car on the lift when he spotted the famous heart surgeon, Dr. Samuel Kaiser, who was standing off to the side, waiting for the service manager. ©OFFICEJOKES.NET

Jerry, who was somewhat of a loud mouth, shouted across the garage, "Hey Kaiser, Is that you? Come over here a minute." ©OFFICEJOKES.NET

The famous surgeon, a bit surprised, walked over to where Jerry was working on the car. Jerry, in a loud voice that all could hear, said argumentatively, "So, Mr. fancy doctor, look at this work. Like you, I too take valves out, grind them, put in new parts, and when I'm finished, this baby will purr like a kitten. So how come you get the big bucks, when you and I are doing basically the same work?" ©OFFICEJOKES.NET

Dr. Kaiser, very embarrassed, shook his head and replied, "Try doing your work with the engine running."
