Before their concert in Kansas City, the Foo Fighters dressed up and played a song to the Westboro Baptist Church protestors. The song, “Keep It Clean,” not only features a bit of salty language, but also was used in the intro to their porn parody promo video. Gotta love the speech in the middle too: “I don’t care if you’re black or white or purple, whether you’re Pennsylvanian or Transylvanian, whether you’re Lady Gaga or Lady Antebellum: it takes all kinds.”
