I've been having fun watching "Weird Al" Yankovic's eight new videos in eight days campaign for his new album. And I like this one (including the wonderful two-second shot at Alanis Morrisette) a lot. Words and music by the Wieird One, animation by Jarrett Heather.
But this song, by Tom Lehrer of the p3 pantheon of gods, remains the definitive grammar song. It's from the old Children's Television Workshop series The Electric Company, which boasted regulars like Morgan Freeman and Rita Moreno. And it's in klezmer style. Take that, Weird Al.
