I like Weird Al Yankovic - Smells Like Nirvana "Off the Deep End"
That song does a really good job of parodying Nirvana. I won't spoil the humor by posting the lyrics up, but get the song and you'll see what I mean.
Actually, I'll post one line.
"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"
