Hi Lynn!
True, but even he has his limits, and it's Lois's nature to push them.
LOIS: The author is not suggesting that my food is much crunchier that an actual mountain of rocks, is she?
CLARK: /crunch crunch/ I don’t know, Lois. Some of those asteroids are made up of a lot of ice holding the rocks together. And metal inlays, those are more chewy than crunchy. /slurps/ Could you hand me the heavy duty toothpick, please? I think there’s a bit of gold fiber stuck back there.
