I used to think that the song "Helicopter" by Bloc Party was all about cows for some reason. At the beginning, when it said "North to south" i thought it said "Not his cow" like a farmer not wanting his cow to be killed. What really confused me was the chorus which i thought was saying "Are you happy for a moo-cow?" rather than "Are you hoping for a miracle?" also, in a verse i thought it said "Master's tired of milk and shaving"
