Episode: "Whale Whores” (s13e11)
Original Air Date: October 28, 2009
Cartman's rendition of “Poker Face” stands toe-to-toe with his congressional ballad “Heat of the Moment,” and overtakes it in Youtube views by a magnitude of fifty. Perhaps what's so surprising and wonderful about it isn't that he sticks so close to the source material but that someone playing Rock Band actually hit the notes.
Rock Band vocal solos are intended for the most amateur singers, even too amateur for karaoke night at a local bar. To hear a short, fat fourth grader belt out some Gaga with such accuracy is a ringing endorsement for the song and the game that Cartman delivers it through.
