When my cousins and I were younger we always wanted to spend the night over at one or the other's house. Well, our parents would get around it by saying we could the "second Tuesday of next week." Now, it took us quite a while to finally realize there was no second Tuesday in ANY week....needless to say, it still brings me a chuckle when I think about it.
