Did that just happen?
Took my dad's 10-speed bicycle out for a ride one afternoon when I was 12 or 13. Didn't know the shift mechanism well and was periodically looking down at the levers on the frame (ah, old school). Coming down the drive at a wobbly pace whilst shifting, out of the top of my visual field I see something that looked like a frog's head on the right of the front wheel and its hind quarters on the left side of the front wheel. Being a gravel drive, it was hard to tell if I had seen that or if it was an illusion formed by the gravel. So, I stopped a short ways ahead, and went back on foot. I found two things; one, that there was an ex-frog whose back conformed to a bicycle tire rut and, two, it was not an illusion.
