A Riddle For You All

This is how I broke the news that I was pregnant to some of my family and friends:

I'm a riddle in nine syllables,

An elephant, a ponderous house,

A melon strolling on two tendrils.

O red fruit, ivory, fine timbers!

This loaf's big with its yeasty rising.

Money's new-minted in this fat purse.

I'm a means, a stage, a cow in calf.

I've eaten a bag of green apples,

Boarded the train there's no getting off.
