Star: John Travolta
Product: Safeguard soap
Year: 1972
Sample lyric: “It’s better than leading bars with hexachlorophene”
Ah, a simpler time, when long chemical names could be pushed into catchy couplets. Watching a young Travolta lather up in the locker room, it’s hard not to think of the part in 1978’s Grease when Danny tries to be athletic—but without any of the worldliness brought by the Thunderbirds’ leader. (Especially at 0:07. Sing it!)
