Wearing tiny polyester pants affects the sex life of rats. Rocks have distinct brand personalities. Dragonflies have a fatal attraction to black tombstones. Things may look different when you bend over and view them between your legs.

These are just some of the scientific revelations that were celebrated, tongue firmly in check, at the 26th First Annual Ig Nobel Prize ceremony on September 22. The awards are organized by the magazine Annals of Improbable Research, which combs through thousands of scientific journals for amusing (but not necessarily trivial) research news. Recent articles have covered the kissing games of adolescents in Ohio, the health benefits of dirty water and smoking, and feminist glaciers.

This year’s awards—given in honor of “achievements that first make people laugh then make them think”—went to a man who lived as a goat, a man who wrote a multi-volume autobiography on the pleasures of collecting flies, and a team that studied the reception of pseudo-profound bullshit. The awards were held at Harvard University’s Sanders Theatre during a hijinx-filled live webcast that featured genuine Nobel laureates giving out the awards (live tweets gave a taste of the proceedings). The full list is on the Ig Nobel website, but here are a few highlights—and if you happen to be near MIT on September 24, there will be a "half-afternoon" of informal public lectures by the winners.
