Here's an embarrassing confession. The other day I noticed a strange clicking noise and couldn't figure out where it was coming from. When I got back from my ride, while in the driveway I unclipped one foot and was bouncing on the crank with the other foot, trying to figure out if it was the crank, the headset, what was making the noise. Well my body weight shifted a bit more to the right than I was planning on and I fell over and put a number of scratches on the bike components (RD, pedal, saddle, brake lever).
At least I'll be constantly reminded of my stupidity when I see the scratches.
I'll probably try to make up a good story incase anyone asks what happened to my saddle (which took the worst of it).
