Grandma is in the fish?

The other night as we were reading the selected bedtime story of "Wynken, Blynken, and Nod," Josiah pointed to one of the herring fish and said, "Grandma is in the fish." As you can imagine, I was quite confused. I suggested several permutations of what he might be trying to say: "Do you mean Grandma told you about this fish?" "Do you mean this fish has a grandma?" But he insisted, "Grandma is inside the fish." So I finally gave up, envisioning a miniature grandmotherly type, small enough to fit inside a herring fish. "Okay." Satisfied that I had accepted his statement as he intended it, Josiah proceeded to tell me that the fish would swim to the beach and spit out Grandma and then the fish would swim back to the rest of the fish in the sea. There's that lightbulb over my head moment - click! - as I remembered how fond he's been of his Bible lately. "Oh, okay, buddy. I see. That probably wouldn't happen to Grandma. I think it has only happened to Jonah in the entire history of the world…" "Now cast your nets wherever you wish - never afeared are we. So said the stars to the fishermen three, Wynken, Blynken, and Nod." -Shauen
