A skunk sat on a stump and thunk the stump stunk,
but the stump thunk the skunk stunk.

A flea and a fly flew up in a flue.
Said the flea, "Let us fly!"
Said the fly, "Let us flee!"
So they flew through a flaw in the flue.

A tree toad loved a she-toad
Who lived up in a tree.
He was a two-toed tree toad
But a three-toed toad was she.
The two-toed tree toad tried to win
The three-toed she-toad's heart,
For the two-toed tree toad loved the ground
That the three-toed tree toad trod.
But the two-toed tree toad tried in vain.
He couldn't please her whim.
From her tree toad bower
With her three-toed power
The she-toad vetoed him.

those should keep you busy for a while!

Hippo, I love you.
