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 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, yadayada, yahyah
Ayiyah
