Ogden Nash produced at least five examples of what he called a limick, a sort of condensed limerick with four lines of dimetric anaepests and three masculine or feminine rhymes, aaba, as in:

Two nudists of Dover,
Being purple all over
Were munched by a cow
When mistaken for clover.

Or

An old person of Troy
In the bath is so coy
That it doesn’t know yet
If it’s a girl or a boy.
