Текст песни Smells Like Nirvana - "Weird Al" Yankovic

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
Blergh
Haai

It's unintelligible
I just can't get it through my skull
It's hard to bargle nawdle zouss
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, 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, hodinawa
Odinaya, yodinaya
Yadda-yadda, yah-yah
Aye-yaah
