Butt, butt, butt, it's only smokers who litter. They must be the ones throwing out these "trucker" bombs, and the Walmart bags, and the bottles of Colt 44, and fast food wrappers, etc.... And blame those dirty baby diapers on evil smoking babies. Everyone knows that saintly non-smoking babies always deposit their diapers in the trash where it belongs. And heck, the poop of non-smoking babies don't even stink.
