Текст песни Weird Al - 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
