Patches
Puzzler time.
This one is random. And also very brief. If you blink, you'll miss it.
So, I was on vacation years ago. I was walking down the street and there was a guy dressed like a pirate standing outside a bar. He was in the full get up. Hat, parrot, pantaloons, and eye patch. The whole deal.
And this got me thinking.
As everyone knows, sailors and pirates of yesteryear very often had patches over one eye. It is in all the movies, all the books, everything about sailors and pirates from the olden days, many of them had eye patches.
So the puzzler is, why is it that old time sailors and pirates frequently had no eye sight in one eye so that they had to wear a patch?
