Humor for today

A mechanic was
removing a cylinder-head from the motor of a Harley motorcycle when he spotted a well-known heart surgeon
in his shop.

The heart surgeon 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 heart surgeon , 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 open 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 get the really big bucks when you and I are doing basically the same work?"

The heart surgeon paused, smiled and leaned over, then whispered to the
mechanic...

"Try doing it with the engine running."
