We all have done it at some stage of our riding life

Another similar indecent occurred to me. I was riding my old Norton 750 and had rolled up into the yard. (I lived in the country and so my front yard was my parking.) The grass was damp and I grabbed a handful of natural, unmodified, front Norton disk brake. The effect was violent and instant. One minuet I was rolling to a stop and the next second I was on the ground, under the bike and looking a grass up close and personal. Of course the first thing I did was jump up and see if anyone saw me. It was embarrassing and oh so stupid.

My experience was not embarrassing - but easily could have been.
In 1982 my daily ride was a Suzuki Katana 1000. I had broken both bones in my lower left leg so was in plaster. After a few months I started to ride again.
I could change down with the heel of my cast but not change up. Solution? A short length of small 5mm sailing rope tied to the toe-piece and fixed to the tank/seat interface - used my left hand pull pull up to change. Obviously had to be clutchless up changes but, hey, no problem!
I was just leaving a mate's workplace (smooth concrete floor/driveway). He had waved and had turned away. On the way out I hit a small patch of some fluid and the bike went down on the LH side, pivoted under power on the footpeg 180 degrees (I couldn't put my cast down) hit dry again, stood up and I rode back into his shop - much to his confusion.
All he heard was a brief "rev" followed by my re-entry. Still makes me laugh today.
Cheers
