The mother came on her little son who was standing thoughtfully before
the gooseberry bush in the garden. She noted that his expression was

"What about, little man?"
"Have gooseberries any legs, muvver?"
"Why, no! Of course not, dear."

trouble deepened, as he spoke again:
"Then, muvver, I fink I've swallowed a catapillar."
