I can't believe you guys are overlooking the great contribution to world literature made by Ogden Nash. Examples:

The cow is of the bovine ilk;
One end is moo, the other milk.

As well as that perfect example of High Culture:

The turtle live 'twixt plated decks
Which practically conceal its sex.
I think it clever of the turtle
In such a fix, to be so fertile.

Shakespeare, eat your lacy-cufed heart out.
