Kenny Rogers & Dolly Parton, "Islands in the Stream" (1983)
The classic duet, celebrating silver-fox romance with intense sexual imagery. (How exactly do you use that "fine tooth comb," Kenny?) This song lives on in every karaoke bar on earth. And here's to Ol' Dirty Bastard, Pras and Mya for turning it into the 1998 hip-hop classic "Ghetto Supastar."
