Thank you to Barry for this joke contribution.

A Lexus mechanic was removing a cylinder head from the motor of a LS460 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 car 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.

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 cardiologist paused, leaned over, and then whispered to the mechanic,
“Try doing it with the engine running.”
