PROPOSED ACCIDENT

A boy walks through a park, stops in a convenience store, buys one small bottle of Heinz tomato ketchup, and leaves. He crosses the road, and is immediately hit by a car. His head hits the windscreen, then he slides backwards off the car's bonnet, and comes to rest beside the bumper and the front right wheel. The driver leaps from the vehicle and runs to his side exclaiming 'Oh my god, there's blood. I've killed him. Somebody call an ambulance.' The boy opens his eyes and says,

'It's only tomato ketchup.'
