Chimpanzee Sanctuary Northwest, a chimp-rights group, is assailing Sports Illustrated with a vicious letter-writing campaign! The group is upset that the magazine used a macaque (FANCY WORD FOR "MONKEY") and a bear in its photo shoot for this year's Swimsuit Issue [Folio]. S.I. is like, whoa! We take care of the animals, and besides, what mammal wouldn't be happy nestled up against the thighs of a swimsuit model? The two bear/ model-relations pictures, which have caused all the human outrage, after the jump. The bear does look kind of annoyed by that muzzle.
