Arrest them all on misdeanor charges of mischef!
Please reconsider this advice. I routinely move Hil, Bill and company from prominent displays. I frequently place conservative authors over the Pinko books on display. Turn about is fair play.
The problem with that idea is that it would be the managers of the bookstores who would have to do it. The same ones who are putting mulitiple fronts of "My Lies", by WBJC, on the shelves right up in the front of the stores usually. They aren't going to have the "pranksters" arrested. They probably wouldn't be overly quick about moving "Unfit for Command" back where it belongs either.
"mischef"?
Did they burn the mashed potatoes?
