Are you sick of hearing people tell you that feminists need to get over themselves, or grow a sense of humor, or stop taking things so seriously? Just give them an ironic theme song: Nellie McKay's "Mother of Pearl." (Click on the play button at the bottom of the post -- and for hearing-impaired readers or anyone else who wants it, here's a link to the lyrics.) In a breathy, sweeter-than-sugar voice, McKay sings a playful little show tune with lines like "Feminists spread vicious lies and rumors," and "[Feminists] have a tumor on their funny bone," while a group of hecklers in the background responds, "Lighten up, ladies!" or "Sing us a new one!" (My favorite line: "They say objectification isn't funny," to which the peanut gallery responds, "It's hot!") This is the perfect song to play for people who think women need to put a sock in it: They'll want to agree with the words that she's (sarcastically) singing, but will probably have difficulty sitting through the dance solo.
It reminds me of a business card my mechanic likes to give out to people who complain to him. "Your story has touched my heart," it says, in fancy-looking script. "Never before have I met anyone with more problems than you. Please accept this token of my sincere sympathy." (Then it lists his contact information.) I find McCay's song to be just as deliciously sarcastic.
