-Mechanic vs. Mechanic. A motorcycle mechanic was removing a cylinder-head from the motor of a Harley-Davidson when he spotted a well-known cardiologist in his shop. The cardiologist was there waiting for the service manager to come and take a look at his bike when the mechanic shouted across the garage, "Hey Doc, want to take a look at this?" The cardiologist, a bit surprised, walked over to where the mechanic was working on the motorcycle. The mechanic straightened up, wiped his hands on a rag and asked, "So Doc, look at this engine. I opened its heart, take the valves out, repair any damage, and then put them back in, and when I finish, it works just like new. "So how come I make $39,675 a year and you make $1,695,000 when you and I are doing basically the same work?" The cardiologist paused, leaned over, and then whispered to the mechanic, "Try doing it with the engine running."
