I'm cribbing this from John Derbyshire, but so what? It's one of those things that makes you realize that no matter how different things seem today, they probably aren't as different as you think.

About 30 years ago, author Alan Coren complained to his agent that none of his books sold very well. His agent told him that there were only three categories of book that consistently sold well: books about golf, books about cats, and books about Nazis.

Coren titled his next book Golfing for Cats and put a big swastika on the cover.

No lie. You can find it listed in online used bookstores. The only wonder to me is that it's out of print.
