An engineer was removing the engine parts from a car when he saw a famous heart surgeon in his shop.
Engineer went to the heart surgeon and said, “Look at this engine, I opened its heart, took the valves out, repaired and put them back”.
So why do I get such a small salary and you get huge sums ?”
The doctor smiled at the engineer and came close to engineer’s ear and said, “Try the same when the engine is running.”
The engineer smiled back, came close to doctors ear and said, “I can pick any dead engine and make it alive, can you ??? And Doctor do not forget that all your instruments and machines have been designed and got manufactured by enginers.”
