I heard this the other day. An eminant heart surgeon collected his posh car from the garage after a service, and the mechanic got talking to him.
Mech. "Our jobs are kind of similar aren't they. We both work with valves, you put new ones in hearts, and me in engines. We both work with great precision. If we fail, lives could be at stake. An engine is like a pump with pistons, and must not leak etc. Yes, we're quite similar really, so why is it I get paid a pittance, and you get a fortune?" The heart surgeon thought for a second, leaned forward and said, " Yes, but do you do it with the engine running?"
Don't usually post jokes, but I quite like this, hope you do.
Regards, Mike

Actually, they both work on the "engines" while stopped. During most types of open heart surgery the heart is "stopped" with an ice-cold cardioplegia solution. The function of the heart and lungs is taken over by the cardiopulmonary bypass pump (albeit for a finite time).
