About You're a Mean One, Mr. Grinch

"You're a Mean One, Mr. Grinch" is a Christmas song that was originally written and composed for the 1966 cartoon special Dr. Seuss' How the Grinch Stole Christmas! The lyrics were written by Theodor "Dr. Seuss" Geisel, the music was composed by Albert Hague, and the song was performed by Thurl Ravenscroft. The song's lyrics describe the Grinch as being unpleasant, foul-smelling, bad-mannered, despicable, and diabolical, using increasingly creative put-downs, metaphors, similes and off-hand comments by the singer, beginning with the opening line "you're a mean one, Mr. Grinch".

Because Ravenscroft was not credited in the closing credits of the special, it is often mistakenly attributed to Boris Karloff, who served as narrator and the voice of the Grinch in the special but who himself was not a trained singer. Until Ravenscroft was publicly credited, Tennessee Ernie Ford was also speculated to be the voice behind the song. The soundtrack to the special won the Grammy Award for Best Album for Children at the 10th Annual Grammy Awards.
