A mechanic was removing the engine parts from a motorcycle. When he spotted a famous heart surgeon in his shop, he called him and said, “Look at this engine sir, I opened its heart, took the valves out, repaired them and put them back. So why do I get such small salary and you get such huge amounts for doing the same things ? “
The doctor smiled at the mechanic and came close to the mechanic’s ear and said “Try doing the same when the engine is running”.
