A game loosely based on "Street Hawk", TV's motorbike Knight Rider. The rules; after school, Steve Wild's little brother would ride around the playground on his BMX as close to 200mph as he could get, while we threw rocks at his wheels.
It ended, as all good things must, when Steve launched a set of those elasticated hooks used for securing luggage to roof racks into the front wheel at close range. His brother flew headlong onto the playground. I'm not sure how badly he was hurt because I did the honorable thing and legged it.

My friend Tina's boyfriend was in a band who were called 'Shy-Talk'. Very 80's. The venue of their first gig rang him up to ask the name of the band for the posters. They - of course - misheard, and Cheltenham was awash with 'Shite Hawk' posters. Bonus.
