They are all great, and you can't pick a favorite...
but here are a couple really good ones.
Bear In There by Shel Silverstein
There's a Polar Bear
In our Frigidaire--
He likes it 'cause it's cold in there.
With his seat in the meat
And his face in the fish
And his big hairy paws
In the buttery dish,
He's nibbling the noodles,
He's munching the rice,
He's slurping the soda,
He's licking the ice.
And he lets out a roar
If you open the door.
And it gives me a scare
To know he's in there--
That Polary Bear
In our Fridgitydaire.
Forgotten Language by Shel Silverstein
Once I spoke the language of the flowers,
Once I understood each word the caterpillar said,
Once I smiled in secret at the gossip of the starlings,
And shared a conversation with the housefly in my bed.
Once I heard and answered all the questions of the crickets,
And joined the crying of each falling dying flake of snow,
Once I spoke the language of the flowers. . . .
How did it go?
How did it go?
One of my favorite books is Runny Babbit - A delightful book of poems made up of spoonerisms, where the first parts of words are transposed.
A quick example of this book is,
"Runny be quimble, Runny be nick. Runny cump over the jandlestick."
Silly... but I can't help loving this...
(Ha! That rhymed!)
