Really. Polka?

So, Tianna and I are on our way to work today. (Actually, technically, we were on our way between work, going from SLC to Orem. But that's really neither here nor there.) I'm listening to the radio--a country station, if you're interested. And in the middle of this song, polka music starts playing over it! It was so weird! The station wasn't fuzzy or going in and out or anything. There was just this psychotic addition of polka to country. And it lasted a good thirty seconds. So bizzare.
