A quora of hermit crabs sunned on the beach.
One crab boasted of his new too-large shell, “It is the biggest, the shiniest, the best!”
A squadron of seagulls noticed and dove beachward.
All the crabs in small shells scuttled away, but the crab with the too-large shell could not escape.
Moral: Do not boast of a house for which you are not ready.
