"ABC-DEF-GHI" is a Sesame Street song sung by Big Bird, which was first performed in show's first season and re-recorded several times. In skits featuring this song, Big Bird sees the alphabet (often, written on a board or a sign) and interprets it as a long word that he doesn't understand. He sings it aloud, pronouncing it "ab-ca-def-gi-jeckle-mi-nop-kwer-stoov-wix-iz," attempting to decipher whatever meaning this word may have. He is eventually reassured by the adults that "ABCDEFGHIJKLMNOPQRSTUVWXYZ" is not a word but the alphabet.
