Mechanical Engineer: - "I am sure the gearbox must be broken."

Chemical engineer: - "I do not agree. The issue is in the composition of the fuel."

Electrical engineer: - "You are both wrong! The battery is exhausted."

Computer Engineer: - "What if we get out of the car and then enter again!?"

A programmer had been missing from work for over a week when finally someone noticed and called the cops.
