Wow - "Scary Stories" by Alvin Schwartz is the #1 most-challenged book (well, series)? I loved those things when I was a kid, especially the pictures; I'd find other books with similar titles and I'd get mad because they were never up to the same level of quality. I still remember some of those stories; there was some wild stuff in there...

Oooh, thank you for linking to that poster. Must have it.
