Despite what you may think from the title, this is not just scatological humor. Author Eric Spitzhagel’s latest project is to showcase how various authors view their own assholes. He invited writers to make a sketch and submit it.

The idea was cooked up several months ago, over far too many beers in a San Francisco bar. Some writer friends and I were enjoying a post-book reading cocktail, and though I can't recall anymore who brought it up (or why), we began discussing Kurt Vonnegut's asshole. Not his actual asshole, of course. Rather, his infamous asshole doodle, which first appeared in his brilliant novel Breakfast of Champions.
