25+ years ago, my son, at about 3½, made some remark using a word that surprised us. Pleased, we complemented him on how well he said it. (details long forgotten, but not his response: )

He said, "Yes, I have a lot of words in my mouth!"

My college German professor told of a small boy objecting to his father's choice of a book for a bedtime story:

"Daddy, why did you bring that book I didn't want to be read to out of up for?"
