I learned that octopuses have three hearts. They apparently also have lots of extra neurons in their tentacles. Neat trick, that. I also learned that Jupiter now has sixty-three moons! I am just thankful I didn't have to read *all* the names to the Spawn. I would have, but we'd already done the names of most of the other moons in the solar system. A big thank you to the Spawn for getting me started.
Oh, and I also learned that sheep do indeed fit themselves through relatively small spaces, no matter what the Better Half might think. But they're very susceptible to being lured back into the pasture with sheep crack (otherwise known as a handful of grains).
