A young mechanic was repairing the engine of a cardiac surgeon’s BMW while the owner waited. The mechanic yelled across the floor to the doctor, “Hey Doc, can I ask you something?”
The surgeon was a bit surprised but he walked over to the mechanic. The mechanic straightened himself up and wiped his hands with a rag. “Look at this engine doc,” he said. “I open hearts, take out valves, fix ’em, and put ’em back in. When I’m done they’ll work just like new. So how come you get the big bucks when I barely have enough to get by?”
The doctor leaned in close to the young man, smiled, and said, “Try it with the engine running.”
