Limericks ~ five-line humorous poem: a five-line humorous poem with a characteristic rhythm, often dealing with a risqué subject and typically opening with a line such as "There was a young lady called Jenny."
Lines one, two, and five rhyme with each other and have three metrical feet, and lines three and four rhyme with each other and have two metrical feet.

I think these are fun, had to do one for English one year, and thought I'd share. Feel free to post your own too! ^^

-Broken Bonds-
There once was a pup in such pain,
that the blood spilled like rain.
In his anger and fury,
he killed his tormentors in a hurry.
His anger he could finally contain.
