"Oh, so one's a Daddy Long-legs and the other one is a Mommy Long-legs?"

"Well, no dear, actually both of them are Daddy Long-legs," explained her father.

Lucy thought for a moment, then suddenly stomped on the two spiders with both feet. With a stern look, Lucy exclaimed, "Well, we're not having THAT sort of thing going on in this garden!"
