All Write, Already!

(The title has nothing to do with what follows, it just amused me.)

The square peg had tried and tried, but it could not get itself into that inviting round hole. For ages untold it tried, until one day it got an idea. It realized that if it could file its edges sufficiently, it would be able finally to get in. But it had no tools. Oh, to be so close!

Then inspiration struck again, and the square peg began rubbing its corners against the rough rim of the round hole. For eons it did so, until one, then another, then all four of its once right-angled corners were eroded as round as a seven-year-old's estimate of how many grains of sand lay on the beach. Triumphantly, the square peg inserted itself into the round hole.

Or it would have, had the hole not been filled halfway to the top with sawdust.
