Who knows, who knows
Hanging from the rafters like a church bell
You talk like a fish in nonsensical bubbles

Why won't you ever go all the way?
Who knows what goes on in her pretty little head
Who knows what goes on in her pretty little head

You cause only trouble, you bring only suffering
Who knows what goes on in her pretty little head
Who knows what goes on, who knows what goes on
Who knows what goes on in her pretty little head
Who knows what goes on in her pretty little head
Who knows what goes on, who knows what goes on
Who knows what goes on in her pretty little head
Who knows what goes on in her pretty little head
Just get in the spaceship and stop bleeding
Who knows, who knows
And screaming blue murder at newly weds
Who knows what goes on in her pretty little head
Who knows, who knows, who knows, who knows
Who knows what goes on, who knows what goes on
Who knows what goes on in her pretty little head
You kick like a mule, short of an Oscar
Who knows what goes on in her pretty little head
Who knows what goes on in her pretty little head
Why do you never sing in church on Sundays?

You're light years away from reality
Then blow the word bitch through your smoke ring

Who knows what goes on in her pretty little head
Lonely, lost in a white Russian galaxy
You're floating towards heavenly hell

Who knows what goes on, who knows what goes on
