A mechanic, an engineer and a computer scientist are travelling together in a car, when the motor suddenly fails.
The mechanic and engineer each try various techniques to restart the car…
“Pump the accelerator a couple of times”, says the mechanic.
“No,” replies the engineer, “turn the ignition key without touching the pedal…”
The car refuses to start.
After the failure of several more attempts, the computer scientist confidently announced his solution.
“Let’s all get out of the car, then get back in.”
