There's a story for the pub!
Its amazing what people get up from sometimes. When I was as comprehensive some decades ago,I was cycling home with a mate along a busy road. I turned to speak to him and he had vanished....a passing bus had caught him,sucked him and his bike underneath and then dragged him about 200 yards up the road before depositing him out the back of the bus. Several people rushed up expecting the worst only to see him get up right as rain bar a few scratches & bruises,a mangled bike and cracked specs.
