define: Limerick

For a good definition of the limerick, see Wikipedia (as usual):

Limerick (poetry) - Wikipedia, the free encyclopedia: A limerick is a five-line, often humorous and ribald poem with a strict meter, popularized by Edward Lear and Ogden Nash. The rhyme scheme is usually “A-A-B-B-A”, with a rather rigid meter. The first, second, and fifth lines are three metrical feet; the third and fourth two metrical feet.

Lilmerick poetry to come, hopefully, at the daily poem.
