Humor on a Monday (Because we all need humor on Monday's)

A mechanic was removing a cylinder head from the motor of a Harley motorcycle when spotted a well-known heart surgeon in his shop.  The surgeon was there, waiting for the service manager to come and take a look at his bike.

The mechanic shouted across the garage, "Hey, Doc can I ask you a question?" The surgeon a bit surprised, walked over to the mechanic working on the motorcycle.  The mechanic straightened up, wiped his hands on a rag and asked, "So Doc, look at this engine.  I open its heart, takes valves out, fix 'em, put 'em back in, and when I finish, it works just like new.  So how come I get such a small salary and you get the really big bucks, when you and I are basically doing the same work?"  The surgeon paused, smiled and leaned over, and whispered to the mechanic..."Try doing it with the engine running."
