…of the guy with a prolapsed rectum and what does it have to do with baby poop?
What’s really weird is that, if I click on your link, there’s an ad there where the photo was.
I’m not getting the ad, but the photo is not a guy with a prolapsed rectum, he’s sitting on a section of about 8" pipe. But it doesn’t really have anything to do with either section of Cecil’s column. Wierd.
It’s just an advertisement. The online columns have included them in that space for a month or two now. Most of them are more obviously ads than this one. When I first saw this one, I wondered if Slug has taken up photography.
I saw that “advert” and didn’t know what the hell it was. I assumed it was the usual weirdness.
Look! Up in the sky! It’s a bird–it’s a plane–it’s a WHOOSH! 
I know. It just reminded me of one of the pictures on rotten.com which actually didn’t involve pipe, that I know of.
