Hmm ...

Once upon a time there were these things called legs. Way I heard tell, they used to be used for walking through the woods. Old Maine folk used to use their legs to go for miles and miles through the woods, and bogs, and swamps and hills, and cliffs. Nothing but legs. All's it took was a strong pair of legs and a happy heart. Kids loved it. They ran and ran and ran.

Now all the kids are so fat and out of shape they can barely run to the end of the driveway without running out of breath. Parents are even worse.

Funny as in peculiar.
