Butter lambs

This year's butter lambs.

A classic:
Betty Botter bought some butter
But she said this butter's bitter
If I put it in my batter
It will make my batter bitter.
But a bit of better butter
Will surely make my batter better.

So she bought a bit of butter
Better than her bitter butter
And she put it in her batter
And her batter was not bitter.
So t'was better Betty Botter
Bought a bit of better butter.
