A mechanical engineer, an electrical engineer and a software engineer
are traveling in an old Fiat 500 (Bambino) when all of the sudden the car
backfires and comes to a halt. The mechanical engineer says "Ah! It's probably a problem with the valves, or the piston!".
The electrical engineer says "Nonsense! It's most probably a problem with the spark plugs or the battery!".
The software engineer says "How about we all get out of the car, and get back in again".
