Stupid stuff you thought about as a child

[Cryptic]

Once while driving through Wisconsin, I asked my dad why there were no deer zinging across the road. He seemed a bit puzzled, and said, we may see some, but they usually just stand in the ditch; we'll slow down if they run in front of us.

He started laughing pretty hard the next time we passed a Deer Xing sign that night, though. He laughed at me all night! Oh the humiliation!
