Who's More Stupider?

The chimp?

But then there’s Santino, a 30-year-old male chimpanzee at the Furuvik Zoo on the Baltic coast of Sweden. As Mathias Osvath of Lund University reports in Current Biology, Santino, the zoo’s dominant chimp, has been calmly planning rock-throwing attacks against zoo visitors for the past 11 years. The behavior started becoming a real problem in 1997, when the chimp threw stones at the visitors across a moat several times as part of dominance displays, when he became agitated. Zoo officials found five caches in the chimps’ activity area, of three to eight stones each. Subsequent monitoring showed that in the early morning, before the zoo opened, Santino would collect stones and stockpile them. Later in the day he would hurl them at visitors.

Or these morons from West Haven?

Five Milford teens went on a vandalism spree this weekend causing tens of thousands of dollars in damage by throwing softball-sized rocks at parked motor vehicles along the West Haven-Milford border, smashing windshields, ripping off mirrors and causing ample amounts of body damage to some vehicles. The five teens, all males, were arrested -- with other rocks still stockpiled in their car -- by West Haven police early Sunday morning and charged with dozens of counts of criminal mischief. West Haven police said at least 65 vehicles were damaged.

IQ-wise I'd say it's a wash. But at least the chimp had a good reason.
