Above, the official front page of Sam Zell's media concern, Tribune Company, renamed, today, ZellCoMediaEnterprise. Their false front page amused us the most primarily for its thinly-concealed tone of pessimism&mcash;check out the Tribune DEBToMETER! Also: funny pictures of dogs. Bucking the internet cat trend! After the jump, a couple more of the better-crafted 2008 April Fool's Jokes of the Web:

• Hipster Book Club was pretty funny today. Our favorite post, primarily because of its use of the word "limned," is this book review by "Juniko Katutani."

• The UK papers went over-the-top, with the Telegraph and the Mirror collaborating with the BBC on a "flying penguins" story that was just an ad for the BBC.
