If you are a viewer of Japanese television, you have no doubt seen a pair of celebrities known as the Kano sisters. Single-handedly -- or perhaps double-handedly is more appropriate -- these two have lent new meaning to the term "boob tube."

For older sister Kyoko and younger sister Mika have only one endearing trait (OK, technically two). They don't sing. They don't act. They don't even show the prizes behind curtain No. 1. Their claim to fame is merely this . . .

They have large breasts.
