One of the best little kid quotes I've heard in a while:

A friend's preschool-age daughter was practicing writing simple words in a notebook. Along with her name and the usual "cat" and such, she wrote down "j-o-d" and asked her mother what it spelled. Her mother said it spelled "jod" but that it really wasn't a word. No, the child replied, it spelled "juggle." Her mother carefully corrected her, taking the crayon and spelling out "juggle" for her while sounding out the syllables. The girl looked at it for a moment, then went back to writing. A few minutes later, she again wrote down "j-o-d" and asked her mother what it spelled. I told you, her mother patiently replied, it spells "jod" but that's not really a word. The girl snatched up the notebook and slammed it down on the floor. No, Mommy, she cried, I told you it spells "juggle." I'm not going to help you if you won't even try.
