At the beginning of the song, Bono counts off in Spanish "Unos, dos, tres, catorce!" In English, this translates to "some, two, three, fourteen!" When asked about this oddity in an interview for Rolling Stone, Bono replied "there may have been some alcohol involved". Some sources have suggested that as the first words spoken on the album, the lyrical choice was a deliberate nod to Exodus 3:14 (the first Testament (Old) of the Christian Bible, second book, third chapter, fourteenth verse), whereby after Moses asks God's name, God responds "I Am that I Am". This theory is supported by the fact the final track on the How to Dismantle an Atomic Bomb album is titled "Yahweh", another name for the Abrahamic god.
