I see Barney and Tinky-Winky (or whateverhisnameis) a more likely couple.

Mary, there's probably a market for grandma dolls. I know that when I was a little kid, I did NOT like to be hugged by bony people. I liked my old-lady-hugs warm and fluffy and smelling of baked goods. Never knew my grandparents, but there were plenty of other relatives and family friends. So there might be a chance for a plastic surgery and designer dresses grandma Barbie, but I like the idea of a Cabbage Patch granny with big boobs and possibly little plastic removable teeth.
