Lyrics:

Watch out Billy
The brain police are coming Billy
Watch out Billy
The brain police are coming Billy
Oh, Watch out!

Watch out Billy
The brain police are coming
Watch out Billy
They're coming beside you Billy

Watch out Billy
They're coming beside you Billy

Oh...
Coming down to get your mouth
Watch out Billy
The brain police are coming

I said watch out Billy
They're trying to hold you Billy

I said watch out Billy
They're trying to hold you Billy

Get down
Watch out, Billy...
