A GM mechanic was removing a cylinder head from an LS6 motor when he spotted a well-known cardiac surgeon in his shop. The surgeon was there waiting for the service manager to come and take a look at his car when the mechanic shouted across the garage, "Hey Doc, want to take a look at this?"
The cardiac surgeon, a bit surprised, walked over to where the mechanic was working. The mechanic straightened up, wiped his hands on a rag, and asked, "So Doc, look at this engine. I opened its heart, took the valves out, repaired or replaced anything damaged, and then put everything back in, and when I finished, it worked just like new. So how is it that I make $48,000 a year and you make $1.7M when you and I are doing basically the same work?
The cardiac surgeon paused, leaned in, and said "try doing it with the engine running"
