Weird Al's "Skipper Dan." Not Al's most clever lyrics or concept, but the little pluses add up to mega bonus points: the Divya Srinivasan animation, the late reveal of the chorus, the detailed Disneyland references, the truth. I know and love Divya Srinivasan from many They Might Be Giants music videos, and perhaps you do too.
