Our inner Bart Simpson LOL'd at this new Tumblr, called the Metropolitan Museum of Butts, which (as if it needed explaining) is documenting all of the butts that can be seen in the museum (for free!). Why? "Everybody likes butts. And everybody has a butt," the site's creator explains. The site also includes descriptions so you know what butt you are looking at, for example: "Marble statue of a bearded Hercules, Roman, Flavian period, A.D. 68-98." Hopefully this project will branch out to document butts in other museums as well—we hear The Frick has some real classy butts. In conclusion: butts. [via Neatorama]
