Wah wah wahhhhhhh

I tried to post this from my iTouch last night because I was too lazy to walk up the stairs. Didn't work.

Today Walter said, "Look! A waffle!" while we were driving home from the grocery store.
Me: "A waffle?"
Walt: "Yes!!! A waffle. Look!!"
Me: "OHHHHHHHhhhhh. A waterfall!"

So why does he call waffles "wahckles" ??
