Here's something you don't have happen to you every day. I was driving home minding my own business, when the window to the car in front of me opens. Some sort of giant dog sticks his head out the window. I laugh, because the dog is monstrous. Like a Marmaduke kind of dog, except being a real dog he was much funnier than the one depicted in the comic strip. I don't know how this dog wasn't freezing his giant marmaduke face off.
Everything is fine for a bit, and then I suddenly realize that my windshield is being pelted by something. Big gobs of somethng foamy and wet. This giant dog is foaming at the mouth, slobbering, whatever you want to call it -- and it is whipping backwards from the dog to my windshield. When it hits, it starts to freeze. I make the split-second decision to turn on the wipers -- which, in retrospect, was the absolute worst thing I could have done. The wipers proceeded to smear dog spit from one end of my windshield to another, causing it to freeze instantaneously. Or maybe it just dried out. I wasn't entirely sure, but it was pretty effing disgusting.
To top it off, I was completely out of washer fluid. So I had to drive almost all the way home peering through frozen dog spit. Good times.
