A throwaway dare to 'put the bus window in' was made by a teenage boy to two of his friends, seconds before he boarded a number 33 bus in Hull, in the 1980s.
The boy, Anthony Stevenson, grinned as he made the challenge to his two friends, Gram Hewson and Moys Kenwood. Hewson glanced at Kenwood, and put his bottom lip out a little, as he considered the prank. It was 10:30pm; there was only one passenger on the bus. Hewson raised his eyebrows - a sign a decision had been made.
Kenwood regarded his best friend, and could already hear the glass smashing, the bus braking, and the bus driver's inevitable remonstration.
Stevenson boarded the bus, and the other pair headed off into the night on their bikes. But only round a corner, and, as the bus set off from its starting point, and made a 300-meter almost-circular trip, the two miscreants lay in wait for their unsuspecting friend.
The sound of the approaching but as-yet-unseen bus could be heard, and Hewson selected a broken brick from some rubble. They stood in the shadows until the bus was level with the alley in which they were hidden. As the double-decker lights flashed by, Hewson launched the missile at the top deck, and, with the sounds of falling glass and a somewhat-muffled "Fuckinell!" still in his ears, calmly got on his bike, and pedalled away into the night.
He was already thinking of his cocoa.
