Nate-ism's part deux

Nate has rediscovered his love for "Brown Bear, Brown Bear, What do you see?".  If you don't know it, it is a children's book that starts with the above question.
"I see a red bird looking at me" answers the brown bear.
Then the red bird is asked and he sees a yellow duck looking at him, and so on.  It has a catchy cadence and we read it to him a lot this spring/summer when he was learning colors and animals and animal sounds but now that he has those firmly under his belt, the book had fallen by the wayside in favor of more plot driven thrillers such as  "The Little Lamb" and "The Little Duck".
They must have read it at school, because this weekend, he was in the car sing-songing "
"Brown bear, brown bear, what you hee? I hee Nate yooka at me."

Last night at dinner he was "prinkling yinmin yugar" (sprinkling cinnamon sugar) on his apples and singing the following:
"Yinmin yugar, yinmin yugar what you hee? I hee bopple (bottle) yooka at me."
"Bopple, bopple, what you hee? I hee yid (lid) yooka at me"
"Yid, yid, what you hee? I hee Nate yooka at me"

I love his creativity.  He is just a funny, funny kid.
