Dumbosaurus stoopii
(Extracted from http://wiki.mindcloud.org/wiki/Dumbosaurus_stoopii ;-D)
Dumbosaurus stoopii is incredibly stupid. So stupid, you just won't believe how utterly, mind-squishingly stupid they are. A five hour conversation with a raging fundamentalist will seem like a breeze compared to spending a minute within 50 metres of one of these creatures.
Legends say that other dinosaurs decided to go extinct so they wouldn't have to put up with its asinine shit-brainery.
