It's the funniest thing.
I was driving down the expressway once, and looked at the vehicle to my right. It was a small pickup with one of those caps on it. In the back were a couple dozen Canada geese craning their necks and looking back at me. They'd look around, one head would go down, and another pop up.
It was one of the oddest things I had ever seen. I couldn't figure out if the guy was relocating the geese for the DNR (we have been plagued with geese for about ten years now), or if he had goose-napped them, and was making his getaway.
