This American Life's webisode "Nobody's Family Is Going to Change" shares the story of Dusty and Honey, "two sisters, now in their seventies, who have preserved the same relationship they had as girls...for better or worse." They are not twins, but share identical tastes. They have the same make-up wigs, and eat the same food. "[They] make sure that one never has a larger portion than the other. And one will only have a treat if the other is there to share it with her."
