Limericks are poems with a very exact form. They have five lines. The rhyme scheme is AABBA. The rhythm is a "short long short short long short short long short" in the first, second, and fifth lines. In other words, it has three stressed syllables. The second and third have a different pattern. They are "short long short short long." These have two stressed syllables. See the poems below to get the feel of the rhythm. See POETRY TEACHERS.COM http://www.poetryteachers.com/limerick.html This site by Bruce Lansky shows and explains limericks in a very understandable way. This poetic form was made popular by Edward Lear.
What is a limerick, Mother?
It's a form of verse, said brother
In which lines one and two
Rhyme with five when it's through
And three and four rhyme with each other.
