Clerihew
A Clerihew is a comic verse consisting of two couplets and a specific rhyming scheme, aabb invented by Edmund Clerihew Bentley (1875-1956) at the age of 16. The poem is about/deals with a person/character within the first rhyme. In most cases, the first line names a person, and the second line ends with something that rhymes with the name of the person.
My friends are at the door
but I slipped and hit the floor
through the window they can see
and now they are laughing at me.
