The most recent episode of Radio Lab included this awesome three-part harmony song containing the first hundred or so digits of pi (YouTube version, "music video" YouTube version), which was part of a song written by the comedy/parody musical duo Hard 'n Phirm (consisting of Chris Hardwick and Mike Phirman -- pun!) whose own music video version of the song featured a pi-reciting robot who protected children (perhaps of the house of Gryffindor) from two men in red pointed hats whose job it appeared was to zap the children with death rays, and all made to look like a children's educational TV show from the 80s.  Ya know, pretty standard stuff. #math
