The Yellow Yahoo

This is a letter, the letter Y
Do you know how I know?
It looks sort of like the trunk of a tree
Where the Yellow Yahoos go.
Listen! "Yahoo!" There's a Yahoo now.
I know I heard a sigh. "sigh!"
He's just waking up from a nap in the tree
That looks like a Y.
Watch it, now. He's up for a yell.
"YAHOOOOO! YIPPIE YIPPIE YAHOO!"
What do you think your mother would do
If you yelled like a Yellow Yahoo?

"BOO!"
After a yell and a tasty lunch
The Yellow Yahoo rubbed his tummy.
If you asked him if his lunch was good,
He'd answer, "Yes, quite yummy!"
And then the Yahoo yawned.
He yawned, that Yellow Yahoo.
Then it's up the tree, and fast asleep,
and then to dream about you.
("Clunk!" Falls out of the tree right on his head. Ouch!)
He dreams about you, that Yellow Yahoo.
Through the night, under the sky
By the tree that looks like a Y.
