Input: Text: obligatory this didn't happen today, but 8 years ago, when i was 12. 

start off, my friend and i were the usual 12 year olds. doing dumb shit, shouting profanities at people as we ride etc, yeah we were assholes, but everyone has that stage in life (if anyone is wondering, me and said have been friends for 12 years, and still are to this day.)

so, to the magnificent story.

my friend and i, after a usual uneventful time at school, decided to hang out, as we do. we were playing xbox etc and wanted to go riding on our mountain bikes (we were so cool i know). i lived about 15 houses down the street from a local state school (australia, so it's a public school, no tuition fees) he lived around the corner (i was house #23, he was number #8) we leave from mine and had the plan of riding to the local skate park. we go through the school on our way as it is 40 mins longer to go around the school. 

we get to the school and there was a part of the school near the canteen that was super smooth cement (like smooth as a baby's ass)  it was wet from some rain earlier in the day and was slippery as hell. thinking we were in a tokyo drift movie, we started riding around sliding everywhere, falling off our bikes and having general fun. here is where the fu occurs. a cleaner  (janitor) comes out of nowhere and screams at us for making tyre marks on the cement  (from sliding around). he comes up to us and demands to know where we live etc..

my friend and i are shitting ourselves, thinking were gonna go to jail etc. start to panic. he asks my friend "so where do you live mate, so i can tell your parents and the police what you're doin". in a true bogan accent. my friend pipes up with the funniest shit (at the time) and says "on the corner of suck my dick and lick my ass". i fucking leg it without looking back, ditching the bike as i was already off of it. my friend "attempts" to ride off, i look back for a split second to see my friend mid air, upside down, with a broom handle in his front wheel. i laugh whilst running, which is harder than you think. i was long gone and ran straight home. 15 mins later my friend turns up, with a golf ball size egg on his forehead, i burst into laughter and he gives me my very own egg with his helmet. laughter ensued after and we still talk about it to this day, always laughing whilst trying to tell the story.

2 days later, police turn up to my house asking what we were doing that day, we own up because we honestly believed we did nothing wrong. he warned us about trespassing etc and that was the end of it. good laughs and serious consequences from both our parents (a flogging and getting grounded for 2 weeks)
