If that mocking 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 won't pull,
Mama's gonna buy you a cart and bull.

If that cart and bull 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,
You'll still be the sweetest little baby in town.
