Allan, a mechanic, was removing a cylinder head from a Harley-Davidson
motorbike when he
spotted a world-famous heart surgeon in his garage.

The heart surgeon was waiting for the service manager to come and take
a look at his bike.

Allan shouted across the garage, 'Hey Doc can I ask you a question?'

The famous surgeon, a bit surprised, walked over to Allan.

Allan straightened up, wiped his hands on a rag and asked, 'So Doc,
look at this engine.
I also can open hearts, take valves out, fix'em, put in new parts and
when I finish this
will work just like a new one. So how come I work for a pittance and
you get the really
big money, when you and I are doing basically the same work?'

The surgeon paused, smiled and leaned over and whispered in Allan's
ear, 'Try doing it
with the engine running.'
