Riding along a wall on my BMX on the southend sea front which was about a foot wide, Front feel slips off (God knows how!), for some reason I hardly make any reaction, still holding the bars my face clips the wall on the way down and at that exact moment a coastgard was driving past in a jeep, see's and stop!
Also once my computer broke down, Guys come round to fix it, finds porn, tells mum, you get the idea...
