Mary had a little skirt, with a split right up the side
And every time that mary walked the boys could see her thighs
Mary also had a little skirt with a split right up the front
And every time that mary walked, the boys could see her...

Sorry if I shouldnt have posted this

That was a pretty good one [although, for the life of me, I can't figure out WHAT rhymes with front... ;) ]. Kinda reminds me of those old "there once was a man from Nantucket" limericks....:D
