4. "Romeo" - Dolly Parton and Billy Ray Cyrus (1994) What the ever-loving fuck, Dolly? The queen of country and one of the best songwriters of the modern era doesn't need gimmicks. People love you, Dolly. There's no need to haul future-joke Billy Ray Cyrus to grunt on any of your songs. It's an insult to you and to Shakespeare.
3. "Lady Marmalade" - Christina Aguilera, Lil' Kim, Pink, Mya, and Missy Elliott (2001) We've had a decade to ponder the success of this pile-up of early-aughts sexpots. With that historical perspective, can we objectively say this song was necessary? About as necessary as Mya changing the song's locale from New Orleans to Moulin Rouge. For shame, ladies. And put on some damn pants.
2. "Stan" Eminem and Elton John (2001) Look! Eminem's not homophobic! While gay rights groups protested outside the 2001 Grammy awards because Marshall Mathers was nominated for homophobic rants, they calmed the masses by pairing him with America's Most Accepted Gay Man, Elton John. See? Eminiem can't be a homophobe - he's playing all nice with Elton! That totally makes up for Em saying that New Kids on the Block partook in a lot of fellatio, right?
1. "In the Ghetto" - Elvis and Lisa Marie Presley (2008) Any duet performed between a second-generation singer and a dead parent transcends this list in horribleness. But this ... not enough people know this exists. How can we fight the battle if we don't know the enemy?
Also? That baby with the guns? He uses them to shoot his TVs when he doesn't like what Elmo has to say.
