Is "odd" pronounced the same as "awed"?

Yup, at least by most Canadians. Also homophones, for many* Canadians, are claws/Claus, tot/taught, Mary/merry/marry, and others like it. I once found a really neat map (of the US I think) showing the geographic distributions of a bunch of those vowel sounds. (Maybe chez the American Dialect Society?) Conversely, stock/stack are two different sounds in Canada but many USns (I haven't figured out the geographic pattern yet) pronounce stock so it sounds like stack to me. Anyway, I think for these riddles (they are so neat!) you have to stretch your pronunciation rules a bit!
