Ok, I give up

Can someone please tell me what the difference is between a yam and sweet potato? I always thought they were the same thing, but at the grocery store yesterday, I saw a pile of each. Is one better than the other?
Thanks.

Very interesting. Thanks very much. I bought a sweet potato, but the description matches that of a yam. Maybe the store doesn't know the difference either.;)

I have heard that they are mislabeled in a lot of places.

Gee -- can you tell how exciting my life is when these are the things I hear?
