This is not a joke. Ethan Persoff, archivist of weirdo ephemera and "comics with problems," tells Boing Boing:
Look inside "Karen Santorum's Dirty Book on Manners" at Ethan's website, and you can buy a copy on Amazon. One wonders if future printings will scrub the reference to Paterno (and if the Bono endorsement will stay?)
In 2011 Rick Santorum insulted the planet by comparing traditional marriage to a napkin. But did you know he ALSO wrote a short piece of fiction about "the birth of the napkin" in 2003? And to add further humor: This same book contains an endorsement of the Santorums from Bono of U2, and includes a foreword on "decent manners with children" by Joe Paterno.
