At left is the video for the 3OH!3 song “Don’t Trust Me,” the one that started the whole Helen Keller dance thing because of its lyric, “Shush girl, shut your lips. Do the Helen Keller and talk with your hips.” Click here and you’ll find answers to all your questions about the song and dance. (Seems the band has appropriated the exclamation mark discarded by Panic at the Disco.)
At right is newsreel footage (via BoingBoing) from 1930 featuring Helen Keller herself with her teacher Anne Sullivan. Keller does not move her hips in the clip.
