Okay, there was no whizzing involved, but it's such a great title (and board game).
As Little Dude approached the barbed wire separating the cows from us outside the petting farm, I told him not to touch it. Ever since burning his hand on the curling iron a couple weeks ago, he's come to associate the concept dangerous with the word "hot" (and its accompanying sign), so I told him the wire was hot. I didn't realize how accurate this was until he grabbed the wire and I simultaneously grabbed him to pull him away, and a shock jolted through my arm and down my leg. We later found a sign that had fallen into the grass, warning us that the wire fence was electric.
I don't remember enough from my high school physics class of how electricity works; is it because I grabbed Little Dude that he didn't seem to be bothered by the shock? Because the current only had to travel through his short arm and then through my body instead of all the way through his? He did say "Mooooo" very sadly as I carried him away from the electric fence, but I think that was regret that he couldn't get closer to the cows, not physical pain. Or, you know, maybe he did feel the shock but just didn't care. He's macho like that.

Public Service Announcement: Set Your Clocks Back
No, it's not time for daylight savings. In fact, you don't even need to set your clock back an entire hour--just a minute or so. Why, you ask? Dr. Fob will explain:
Did you know that in Australia toilets flush the wrong way? It's for some complicated reason whose details don't really matter. The only thing you need to know is this: Toilets flush counter-clockwise in the norther hemisphere because of the way the Earth rotates. (And, you know, because that's the way God intended it.)
Did you know that if you spin your toilet-cleaning brush clockwise while the toilet flushes, you can make the water flush the wrong way? It's so simple, I can't believe that no one but me has ever ever thought of it in the history of the world. But trust me, no one has.
Did you know that in Superman: The Movie, Superman flies around the Earth so fast that he makes it spin the wrong way, causing time itself to go backwards? He did this to undo Lois Lane's untimely death in one of the most scientifically sound and narratively satisfying action movie climaxes of all time.
So if you felt something strange this afternoon, this is why: I was cleaning my toilet and I made it flush clockwise. Considering that I am in the northern hemisphere, if you've been paying attention then you understand what this means--I made the Earth spin backwards. And of course by now you've followed the trail of infallible logic to conclude that, for the minute or so that my toilet flushed the wrong way, I made time go backwards.
And that is why you need to set your clocks and watches back a minute.
See, kids, science is fun when you understand it as well as I do!
