Litterers are really stupid

Guess what? Four new lists. None of them are very funny — but your face is. Total count: a paltry 80. What I want to know is, why is it that when I go to the grocery store I see all kinds of litter in the parking lot — (soda bottles, newspapers, flyers, ashtray emptyings, fast food packaging) — but none of it is grocery lists? Obviously, America is full of lazy, moronic litterers, but are grocery lists that private? Why do people take the care to dispose of them properly when they hardly ever dispose of anything properly?
