This is some of the funniest stuff I’ve seen on the Internet in years.
Sean Tejaratchi (@ShittingtonUK on Twitter), maybe best-known for his magazine Crap Hound (which is unrelated to the Cory Doctorow blog with the same name), creates fake ads and book covers. They are in the same vein as SomethingAwful’s Photoshop Phriday (which is still around, believe it or don’t) although a bit more absurd and a bit less 4chan-y.
