So is the joke that morons are likely to get stranded on desert isles, because that is the only way this makes any sense to me. Otherwise it's just the typical representation of evolution with the word morons attached. Maybe morons are funny, but probably not.
Runners-up: Red and Rover, Curtis, Rhymes with Orange, Candorville (Darrin Bell is capable of much wittier and relevant jokes about the quality of the media)
This comic wins a lot of points for the visual in the third panel, which I thought was cute. Otherwise it's the same joke Stephan Pastis has been riffing on all week, but no one else did better today really. And if you're going to use one joke all week, at least make it a good one, which Pastis usually does.
Runners-up: Watch Your Head, Dilbert, Agnes, Non-Sequiter
Other Comics notes: Dennis the Menace and Mother Goose and Grimm both have dumb jokes today, but I wanted to praise them for the visuals. Joey's expression and Attila stuck upside down in a Pringles can both amused me. This doesn't make up for the lame jokes, but at least they did something well.
