Chris Voigt, Executive Director of the Washington State Potato Commission, demonstrating his new all-testicle dietWe have talked quite a bit about Chris Voigt–the potato diet guy. We wrote about him when he started his 20-potato-a-day diet and when he was around the half-way mark. We speculated on whether or not he was going to go crazy from eating nothing but potatoes for 60 days (assuming that, obviously, he would–mostly because we knew we would if our places were reversed).

And more to the point, can a man live on nothing but ribs and whiskey for two months? For a seat on the couch and a free trip to New York, I think I might be willing to try.Hell, I’d probably try it even without the couch and the plane ride. Matter of fact, it’s possible that I already have done that and just never noticed…
