You know what’s always bothered us? Why don’t people throw their underwear at artists instead of just musicians? It’s totally unfair.

Well, for those of you in San Francisco, tonight’s your chance to help rectify this egregious injustice against the making-pretty-things community. Ryan McGinley’s new show “Spring and By Summer Fall” is opening at the Ratio 3 Gallery, and if you don’t show up and pelt him with a rhinestone-encrusted thong then you are part of the problem.
