A limerick poem always has five lines. In a limerick poem, the first, second and fifth line have to rhyme with each other (rhyming examples, bright, night, light). Line three and four should rhyme with each other but should not rhyme with line one, two and five (knit, sit). The arrangement of a limerick poem should be AABBA. A limerick poem line does not have to be a full sentence but instead could be an independent clause or a dependent clause. The rhythm is a very bouncy and fun and the poem it self can be silly. Here is an example of a limerick poem,

There once was a man named Vladimir Putin,                                                                                          Who had a huge, unforgettable sin,                                                                                                                   He liked to loot Kim Jong un                                                                                                                                            Who worked as a former church nun,                                                                                                               But Kim Jong un ended up being Putins secret twin.
