“Then some early wise man saw an animal eating wheat.” That detail had escaped everyone for centuries, apparently. (Note the strange hand position of Miss Sunbeam - it’s as if she fears that letting go of the frame will strand her forever in prehistoric times.) As for the next two panels, we can only imagine the conversation: Did you bring back the gazelle I sent you for? No, but I brought back the stuff he was eating. I thought maybe we could try it. And you let the gazelle go. I was busy getting the mouth-grass. You couldn’t kill the gazelle then get the mouth-grass? Was the mouth-grass going to run off? Look. I’m on to something. I think we can make beer out of this stuff. Then we can get the courage to go next door and steal someone else’s meat. Forget it. They're dead. I was over there this morning.
