Who Are They? lyrics

They say coffee makes me nervous
They say that alcohol spins me 'round
They say that I've got some questionable behavior
And I suspect, it's all written down

Who are they?
And where do they get their information
Who are they?
And where do they get their know
Who are they?
Hey! Where do you get your know
[ Lyrics from: http://www.lyricsmode.com/lyrics/b/buck_o_nine/who_are_they.html ]
They say I should stop acting like a kid
They say, "HEY!" What's behind them shades?
They say I'm always sittin' writin' in a little book
And they've noticed my car it don't have plates

They've showed up at my favorite place for lunch
They know where I like to go to be alone
Are they a network of experts that don't even need a name
And I still don't know who the hell they think they are!?!
