Lyric Smells Like Nirvana

What is this song all about?
Can t figure any lyrics out
How do the words to it go?
I wish you d tell me, I don t know

Don t know, don t know, don t know, oh no
Don t know, don t know, don t know

Now I m mumblin and I m screamin
But I don t know what I m singin
Crank the volume, ears are bleedin
I still don t know what I m singin
We re so loud and incoherent
Man this oughta bug your parents
Yeah

It s unintelligible
I just can t get it through my skull
It s hard to (mumble)
With all these marbles in my mouth

Don t know, don t know, don t know, oh no
Don t know, don t know, don t know

Well we don t sound like Madonna
Here we are now, we re Nirvana
Sing distinctly, we don t wanna
Buy our album, we re Nirvana
A garage band from Seattle
Well it sure beats raisin cattle
Yeah

And I forgot the next verse
Oh well, I guess it pays to rehearse
The lyric sheet s so hard to find
What are the words? oh nevermind

Don t know, don t know, don t know, oh no
Don t know, don t know, don t know

Well I m yellin, and we re playin
But I don t know what I m sayin
What s the message I m conveyin?
Can you tell me what I m sayin?
So have you got some idea?
Didn t think so, well I ll see you
Sayonara
Sayonara
Ayonawa
Odinawa
Yaddayadda
Yaaahyaaah
Ayaaaaah
