I don't know who you think you are
I don't know what you're doing here
[ Lyrics from: http://www.lyricsfreak.com/b/byrds/whats+happening+_20026380.html ]
I don't know what's going 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, I'm not cryin'
Laughin' mostly as you can see
