I feel like such a goober! I have always remembered that Chip had the "chocolate chip" nose, but I have NEVER noticed their teeth! DUH! And it's so obvious, too. You learn something new every day...
I had heard the "Chip's nose looks like a chocolate chip" but I could never remember if the chocolate chip nose was supposed to be the almost-black one or the reddish brown one. Neither one really looked "chocolate chip" colored to me, so obviously I couldn't use that hint!
Then I heard the "two vowels in the name equals two teeth, one vowel in the name equals one tooth, so Da le has two teeth and Chi p has one tooth. Even I couldn't mess that one up!!
