Cobain's initial question about the idea was, "Is it going to be a song about food?"
The song was actually going to be about how nobody could understand Cobain's lyrics.
Cobain was a good sport and allowed Weird Al to do the song.
You've probably heard that story if you're a Behind the Music fan. But, you may not realize how Smells Like Nirvana revitalized Weird Al's career.
In 1989, Weird Al released a movie called UHF and an album that served as the film's soundtrack. Both the movie and the album flopped. Many thought it was essentially be the end of Weird Al's career.
But, 1992's Off The Deep End album, which featured Smells Like Nirvana, launched Weird Al back into the good graces of the American consumer. Smells Like Nirvana became Weird Al's second biggest hit, after Eat It. The album cover parodied Nirvana's Nevermind album cover.
