mechanic;

And if that mockingbird won't sing,

Papa's gonna buy you a diamond ring

And if that diamond ring turns brass,

Papa's gonna buy you a looking glass

And if that looking glass gets broke,

Papa's gonna buy you a billy goat

And if that billy goat won't pull,

Papa's gonna buy you a cart and bull

And if that cart and bull fall down,

You'll still be the sweetest little baby in town
