Bob ran out of gas and a bee flew into the car window. "Are you out of gas", said the bee? "Yes", said Bob. "Gimme a minute", said the bee and flew away.
Minutes later the bee returned with the whole hive and they all flew into the gas tank. Moments later, they all emerged. "Try it now", said the bee. Bob tried and the car started. "Wow", said Bob, "What did you put in there?"
"BP"
