"Oh CRAB," Lucy exclaimed at dinner last night, glancing over at me and Jason as if to try on her new curse word. "I forgot where my locket is," she explained, then got up to go find it.

When she was gone, we cracked up and quickly debated the correction of an intended bad word that wasn't actually a bad word.

When she came back, I asked, "Lucy, what did you just say?"

"I said, 'oh crab.' Because I lost something."

"Well, a crab is a kind of animal. But if you meant to say 'crap,' that's like saying 'poop,' which is not a very nice word."
