It’s real, so watch out.

Monday, a Swedish chimp amassed an arsenal of rocks to hurl at onlookers. The ape began the collecting before dawn, even including chunks of concrete chipped off from his enclosure. Sometime the midday rush, entirely unprovoked, the chimp unleashed a rain of terror on zoo visitors, killing 3 and injuring uncounted others. Fortunately, Sweden is tolerant of chimps and monkeys, so he’s being celebrated for his planning skills.
