Two Nuns went out of their convent to do some grocery shopping They went around the town on their bicycles and had a ball of a time, since they don't usually get to roam about and the convent was soooo boring. So of course they lose track of time wandering around and exploring the town. >""Oh my! We've only ten minutes to get back!"" said the first nun. >""Follow me, I know a shortcut!"" replied the second. They whizz through a narrow alley here, and a narrow alley there, and true enough, they were back just in time to not get into trouble with Mother Superior. >""Wow, I've never come this way before"" panted the first nun. >""I know right?"", said the second. ""It's the *cobblestones*.""
