You're in trouble   Big trouble   Judy's boyfriend got out today   When he was in jail you took his girl away   When he gets back you're gonna have to pay him double   You'd better worry   Or you'll be sorry   He's at the edge of town and he's got a gun   Better get out fast, get up and run   You won't get no help from anyone here son   Better hurry.      Forget the romance   Move your pants   If you don't get out now   You won't get another chance.      Cause he's a mad dog   Don't get into a fight   He's a mad dog   Better shoot on sight   Before he tries to bite.      (Sax Solo)      You'd better run 'til you drop   Don't try to stop   Find a mountain   And climb right up to the top.      Cause he's a mad dog   Don't get into a fight   He's a mad dog   Better shoot on sight   Before he tries to bite.      Use your head   Or you'll be dead   He's at the end of the street, and he's shouting your name   He's lost his girl and you're to blame   Any second now that gun'll spit flame and lead.      Anyhow   It's too late now   With a smile on his face he walks through the door   Fires his gun and your head hits the floor   Did you really think love was worth dying for   It's just trouble.      You'd better run 'til you drop   Don't try to stop   Find a mountain   And climb right up to the top.      Cause he's a mad dog   Don't get into a fight   He's a mad dog   Better shoot on sight   Before he tries to bite.
