Tongue twister: Betty Botter bought some butter...

Betty Botter bought some butter,
But, she said, the butter's bitter;
If I put it in my batter,
it will make my batter bitter.
But, a bit of better butter
will make my batter better.

So, she bought a bit of butter
Better than her bitter butter,
And she put it in her batter
And the batter was not bitter.

So, 'twas better Betty Botter
Bought a bit of better butter.
