This blog/Web review specializes in manipulated art. Its high point occurs on “Photoshop Phriday,” when site regulars put their photo-manipulation skills to work with hilarious results. “Amusement Park Madness” is a series of shots that show rides gone wrong, complete with exploding heads. The graphics archive includes parody motivational posters and artistically revised reading primers; Dick and Jane really have a lot of fun, doing things you wouldn’t expect to see in elementary school. In “Your Band Sucks,” a “psychologist” explains: “The only difference between Nickelback and the Smiths is that Smiths fans dress slightly better and don’t beat their girlfriends as hard.” Some content is just gross, but a sizable chunk is not only coffee-spewing funny, but also occasionally thought-provoking.
