Under the waves at the bottom of the sea, a mother crab scolded her daughter.

"Why are you scurrying side to side in that ridiculous zig-zag walk of yours? Come forward! Walk straight, like other creatures do!"

"But mother," squeaked the little crab, "I learned to walk from you! If you want something different of me...change the example I see!"

And with that, the little crab zig-zig-zig zagged away.
