What's Happening?! ?! Lyrics

I don't know Who you think you are? I don't know What you're doin' here?
I don't know What's goin' on here? I don't know How it's supposed to be?
I, I don't have, the vaguest notion Whose it is Or what it's all for
I don't know And I'm not cryin' Laughin' mostly As you can see
