There are three engineers in a car. a mechanical engineer, an electrical
engineer and a computer engineer. The car, on the way suddenly breaks down.
The mechanical engineer gets down and examines the car thoroughly for about
20 minutes.
"Surely, the problem is in the engine.", he concludes.
The electrical engineer gets down and examines the car for about half an hour
and victoriously says; "definitely there is a battery problem, we have to
recharge the battery."
Finally the computer engineer gets down to see what is wrong and checks the
car for almost an hour and says: "can you please reset the car?"
