Managers, engineers and programmers:

An engineer, a programmer and their manager are driving back from lunch. Suddenly the brakes fail on a hill. The manager frantically swerves back and forth to slow the car down, rubs against the curb, drives onto some grass and finally gets it stopped. They all get out. The manager pulls out his phone and says, "I'll call for a tow truck to take it to a garage that has a factory-certified mechanic who can fix it." The engineer crawls under the car and says, "No wait, I think I can fix it!" The programmer says, "First let's get back in the car and see if we can make it happen again!"
