Little joke by the band, because let's face it, the chord sequences are VERY similar. I know they got stick for it at the time, even when I was growing up I'd heard Teen Spirit referred to as 'More Than A Feeling played by the Pixies'
Hell, there were a few Nirvana songs that people pointed out sounded, ahem, "influenced" by bands Cobain liked..
Its a random intro about songs. Nirvana had to change the title listed on the album to "Waif Me" before Wal-Mart would carry it.
The guitar in this song is basically "Smells Like Teen Spirit" backwards. Cobain thought that if a song was played backwards it would take on a new character.
