WHEN NODDY DRIVES HIS CAR TO MR SPARKS' GARAGE TO FILL HIS CAR UP WITH 4 STAR PETROL ... SUPER UNLEADED; "CAN YOU FILL UP MY CAR WITH THE USUAL PETROL PLEASE MR SPARKS?"; "WELL NODDY, I DON'T SELL 4 STAR PETROL ANYMORE BECAUSE IT'S BAD FOR THE ENVIRONMENT, BUT YOUR CAR CAN TAKE MY SPECIAL HIGH OCTANE SUPER UNLEADED WITHOUT ME HAVING TO ADJUST YOUR ENGINE. I'LL STILL CHARGE SIXPENCE FOR THE PETROL."
