A boy is walking along the road, when a car pulls up alongside him.
"If you get in my car," says the driver, "I'll give you a bag of sweets."
The boy ignores him.
"OK," says the driver. "Get in my car and you can have two bags of sweets and £5."
The boy ignores him.
The driver says, "Listen, if you'll just get in the car, I'll give you all the sweets you want and £20."
The boy turns to the driver and says, "Dad, for the last time, I'm not getting in that Skoda."
