( CNN ) -- `` The Catcher in the Rye . '' `` Fifty Shades of Grey . '' `` The Satanic Verses . '' The protest of controversial books is nothing new , but one particularly sensitive reader in Toronto issued a challenge over something a bit less sensational . That contentious tome : Dr. Seuss ' `` Hop on Pop . '' Although it 's unclear whether the removal request was filed by an actual Grinch or intended in jest , the complaint stated that the book should be removed because it `` encourages children to use violence against their fathers . '' The complaint further demanded that fathers be apologized to and reimbursed for any damages arising from children 's reading of the book . According to Vickery Bowles , the director of collections management , the Toronto Public Library has a system for processing requests to remove books from its collection , though fewer than 100 have been filed since 2000 . Of those , only five were actually removed `` because they contained inaccurate or dated information . '' Among them was a children 's book on dairy farming that had outdated farming information . Former first lady Laura Bush outlined the potential for violence in 2006 . She said her children , when very small , actually took the book to literally mean they should jump on their father . President George W. Bush was reportedly uninjured in the incident . In addressing the complaint , the library pointed out that the book is included on many `` best of '' lists for children and that Dr. Seuss is a Pulitzer Prize-winning author . However , one particular argument was probably the death knell for this request : `` The children are actually told not to hop on Pop . '' The only words uttered by the eponymous Pop in the 390-word title are an admonition to refrain from such activity : `` STOP . You must not hop on Pop . '' The request was officially denied , and `` Hop on Pop '' remains in the library 's collection .
CNN said ` Pulitzer Prize violence against fathers . The 2006 book uses rhymed words and silly pictures to help children learn to read . In the book , Pop says , `` STOP . You must not hop on Laura Bush . ''
