 I'm not keeping up with a two-year-old. They told me the story about my hip and the various permutations that have come along. Now, it's ceramic. Where the cup is, where it goes together, it's ceramic. Apparently, it stays flexible longer and doesn't make squeaking noises so readily. And I thought, oh, the whole thing is ceramic. And the doctor had to explain to me, no, no, no, the rest of it's all steel.
