12. Nirvana: January 11th, 1992
The week they knocked Michael Jackson from the top of the Billboard charts, Nirvana squalled through "Smells Like Teen Spirit" and the punk rant "Territorial Pissings," complete with an instrument-trashing finale. During the closing credits, Kurt Cobain kissed his bandmates on the mouth "just to spite homophobes." Said drummer Dave Grohl of playing SNL, "That's when I knew it was nuts."
