Clerihew poetry has four lines with the rhyme scheme AABB. The first line consists of the name of a person. Sometimes the person's name is the only thing written in the first line. The next three lines should be about that person, and it should be humorous (or an attempt at being humorous - not everyone might think it's funny). You can go here (Wikipedia) for more information.
This particular clerihew that I wrote was inspired by Mr. Darcy in Pride and Prejudice by Jane Austen.
Mr. Fitzwilliam Darcy
Really had to pee,
So he rebuked a woman with whom he danced,
But by then he felt a trickle go down his pants.
