The Foot in the Foreclosure - S5-E8
Audio problem: In the beginning of the episode, Booth introduces his grandfather to Sweets and his grandfather asks, "Where did you get your M.D., in a Cracker Jack box?" You can hear Bones laugh, but her mouth remains closed.
Audio problem: At about 3:47 into the episode, you hear the sound of a slide racking on a pump shotgun, however, when the shotgun wielding woman appears on camera, she is holding a side by side break action double barreled shotgun instead of a pump action.
Answer: Since the palatine bone is a bone that helps form the mouth it has a lot to do with speaking. The shape of it differs a lot depending on your ethnic background. I would guess that they, in the show, meant that the person's bone tells that they were Japanese and that it was "made for the purpose of speaking Japanese." That's what I'd assume anyway. I've studied molecular biology though, so I'm not an expert on bones.
