Strange bedfellows...

I recently found an online coupon for Barnes and Noble, so I decided to buy James Lilek's new book, Interior Desecrators. I was surprised to see the last book listed under other people have bought this item. The last item is Michael Moore's Stupid White men (screenshot here if it changes).

I'm not sure what this means - it seems hard to imagine that any fans of Lilek's political writings are Moore fans. Possible explanations:

1) Lileks has lots of crossover appeal among Moore fans who have never read his political writings

2) Lots of Lileks fans like to buy Moore books so they can make fun of them

3)Barnes and Noble's scipt for "what other people buy" sucks.
