There was a Young Lady whose chin,
Resembled the point of a pin;
So she made it sharp,
And purchased a harp,
And played several tunes with her chin.
What a silly image! Limericks are just plain fun, and while they're often ribald or bawdy, they can be good, clean, ridiculous fun. This is from Lear's "Book of Nonsense." We don't always have to think hard, or at all, to enjoy poetry. There's no point here; apart from the point of the Young Lady's chin, that is.
