Shailene Woodley Is Talking About Her Clay Diet Again

On Monday night's "Late Show," person who loves eating clay, Shailene Woodley, talked about eating clay. Obviously, going into this interview we knew the basic facts about clay: it "bonds to negative isotopes," which Woodley learned from a taxi driver and that, of course, we should all be eating clay (or at least listening to our taxi drivers).

Apparently not everyone in America has started eating clay yet, so, thankfully, David Letterman was around to clear up some important questions, like, where does Shailene even obtain clay in the first place and "how is it different than dirt"?
