We've got a nice red moo-cow-moo,
But doesn't seem just right.
She eats green grass the whole day through
Then gives us milk that's white.
"Red cows, when on blue-grass are fed,
Give white milk." Is this true?
I am so green, when this I read
It straightway made me blue.

We also, have a moo-cow-moo.
She isn't red, but black;
The milk she gives, it isn't white,
But blue,—alas, alack!
Methinks that you'd be black and blue
Had you your due, young fellow;
But matters not the shade or hue,
Just so you're never yellow!
