“Weird Al” Yankovic - Smells Like Nirvana Lyrics

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'
And 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
Boy, this oughta bug your parents
Yeah

It's unintelligible
I just can't get it through my skull
It's hard to bargle, dargle, fftouth
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 raising 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, never mind
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 ya!
Sayonara, sayonara
Ayonawa, adinawa
Odinaya, yodinaya
Yaddayadda, yaaahyaaah
Ayaah!
