Fruit to Bread

You'll never make banana bread.
They can't grow in your head.
Don't try and make them from lead.
Maybe a few pangrapes of read?

Have a loaf you ever seen?
Is there a banana not green?
Will wheat make it lean?
Are they good for your spleen?

You'll smash the bananas.
You'll stir the oven.
Heat the bowl just right.
Still you'll never make banana bread.
