Q-tips out the window

During my morning commute to work, I was behind a burgundy Pontiac. While waiting at a stop light, he opened up his window and threw out a handful of used (I assume) Q-tips. That's about the grossest things I've ever seen. Since spring is nest-building season for the birds here in Indiana, you just know that some poor sparrow or robin is going to have an interior wall that smells like this guy's earwax (or worse).
