When I was a Knd I had a hamster called hammy, one of my mates said that he would give me quite a few bits and bobs to borrow hammy for 2 weeks including a calculator watch.
So of course I accepted, fully expecting the return of hammy the performing hamster, who could do back flips and fall through he mans trap doors in his castle, all sorts of other good stuff.
Anyway after 2 weeks I went to get hammy back, only to be told by my was friend turned worst enemies dad, that the hamster had died.
2 days later said hamster napper/assasin came round to go out on our BMX's and asked to use my toilet. So I of course said yes no problem, of he went to do his business and I got started on the business of slackeing of his brakes then tightening them just enough so that they would hold for normal braking but not extreme braking.
We set of on out trip to arthurs seat and around then came back to the innocent cycle path which is quite steep descent from the main road, half way down the road/path speed picking up nicely I start to brake to turn in, so does my brother and to does the hamster napper/assasin. Which is when the first ping sounded and his back cable came loose, he panicked and jammed on the front frake, did a pretty good endo/wheelie then the front pinged as well. He went hurtling down the hill into a rather large post about 1.5ft across and 5 ft high and lay on the ground moaning.
Laughed so hard I almost pissed and he's lucky I didn't or it would have been on his head!
