Limericks are short and fun poems. People don't know for sure where the name Limerick came from, but most people assume that it came from the name of a county in Ireland called "Limerick." Limericks are popular and fun because they are short, rhyming, funny, and have a unique or bouncy rhythm that makes them easy for anyone to memorize. This form of poetry has five lines. Line one, two, and five rhyme with each other and lines three and four rhyme with each other.
Sample of a Limerick:
The world is a factory farm
And no one can save nature's charm
The harm from this binge
Makes ecologists cringe
And stinks like a raw underarm http://www.limerickpoemsandpoets.com/poems/nature...
