4 engineers are traveling in a car: a Mechanical Engineer, an Electrical Engineer, a Chemical Engineer, and a Computer Engineer. When the car stops working the Mechanical Engineer states, "It must be something with the engine, I'll run out of the car and open the hood". "Ill go with you and make sure the wiring hasn't failed" exclaims the Electrical Engineer. The Chemical Engineer says, "I'll take a fuel sample." They all turn and look to the Computer Engineer and ask his opinion. He stares back blankly and states, "What if we get out of the car then get back in again?"
What do you do to a chemist when he dies? . . . Barium.
