My first mountain bike was a 1992 Cannondale M800 "Beast of the East". Great bike, simple, reliable, effective and light. It was also my first experience with toe clips. Took the bike to my old ladies which is in the same industrial park where we work. At the time there was a lot of factories under construction so there was a lot of fun terrain. So I ask the little woman if she wants to watch me ride, naturally she agrees. So Im wrestling getting the toe clips "just right" and the entire time she is voicing her concern for my safety. Finally as Im approaching this little 10 foot section of sand I snap at her "I know what Im doing" and not 3 seconds later I hit the sand, the bike stops dead, stays upright for a few seconds and we fall over. Not missing a beat she says "So you meant to do that".
To this day I still hear about it.
