Amos: When visiting my uncle's dairy farm as a kid, I remember seeing cow's come "home" on their own (although they were never very far away to begin with) and lining up at the barn door, waiting to get milked. Maybe they're breeding stupider cows nowadays.

I also remember my uncle complaining about the advent of Daylight Savings Time. "How am I going to make my cows come in an hour earlier to be milked?" he said. And he wasn't kidding.

Maybe they're breeding smarter dairy farmers nowadays.
