John was driving down the highway when he ran out of petrol.

He sat there in the driver’s seat wondering what to do next, when a bee flew through his window.

“What seems to be your problem?” the bee asked.

“I’ve run out of petrol,” John replied.

“That’s unfortunate,” the bee said. “However, if you wait here I can help you.”

The bee then flew off, only to return minutes later with an entire swarm of bees. They all flew into his petrol tank, leaving John wondering exactly what was going on.

After a few minutes the swam flew off and the bee said to John: “Try it now”.

John turned his ignition key and the car fired into action immediately.

“Wow,” John exclaimed. “What did you put in the petrol tank?”

The bee smiled and said: “BP of course.”
