  • See?! Now that's the kind of weirdness I was questioning on the long ton page. Who the heck decided an hour would be 40 parts, divided into 12 ounces of 7.5 seconds each?

    And, for that matter, who decided it would be 60 minutes, each made up of 60 seconds? Or that a day would have 24 hours instead of, say, 10? Why twelves and not tens?

  • I know! Who needs minutes? "So let's see...how 'bout we meet at the restaurant at 10 moments and 4 ounces after 5? And don't be late!"

  • I love the idea of time being measured in ounces.

  • This is a very momentous bit of information. I must find a way to incorporate it.
