If that mockin'bird don't sing
Mama's gonna buy you a diamond ring

If that diamond ring turns brass,
Mama's gonna buy you a looking glass

If that looking glass gets broke
Mama's gonna buy you a billy goat

If that billy goat don't pull,
Mama's gonna buy you a cart and mule

If that cart and mule turn over
Mama's gonna buy you a dog named Rover

If that dog named Rover won't bark
Mama's gonna buy you a horse and cart

If that Horse and Cart fall down,
Then you'll be the sweetest little baby in town
