Stealing Magnesium powder out of the chemistry class and setting the school bus on fire with it. Happy days.
Curly Wurlies as big as ladders. Trying to piss over the wall of the urinals in the school playground. Next door's dog jumping up, putting his paws on my shoulders, and licking my face. He was just being friendly but he scared the hell out of me. England getting beat 3-2 by West Germany in extra time, after being 2-0 up, Mexico 1970.
Our magnesium was in little strips, I nicked a few too but just threw them on the fire at home. Best chemistry one was one lunchtime my mate bought two live chickens at the farmers market and let them off in the lab just before our lesson started.
