"Abcdefghijklmnopqrstuvwxyz" is a song sung by Big Bird of Sesame Street.
After stumbling upon the Latin alphabet, which is written out, he mistakes it for a very long word. With marching band-like accompaniment, he breaks into song, pronouncing the word as "(ab-cud-ef-gï)(jek'l-m'nâp-kwûr)(stööv-wik-ziz)." His brilliance as a bird, he thinks, will become known to all the world if he can ascertain the word's meaning.
