Dave Pilkey's beloved "Captain Underpants" series, about two fourth graders who hypnotize their principal into an underwear-sporting superhero, has topped the American Library Association's annual list of "frequently challenged books." Complaints targeting "Captain Underpants" opposed the series' "offensive language."
In honor of National Library Week, the ALA lists the books that have had complaints filed against them in a library or school "because of content or appropriateness."
"Captain Underpants" even beat out the best-selling book of 2012, "Fifty Shades of Grey," an erotic novel about a naive college graduate seduced by a wealthy Lothario, which only made it to number 4.
