The limerick is a poem that nearly always aims at the comic, the satirical, or the nonsensical. It is written in anapests, with three feet in the first, second, and fifth line, and two in the third and fourth. Click here for a historical account of the limerick.

Use any search engine and the word "limericks" (n. b. plural) and you will be treated to innumerable examples that are obscene, inane, and (sometimes, mildly)   funny, including non- or antilimericks. Here is one by Edward Lear:

There was an Old Man in a tree,
Who was horribly bored by a Bee;
When they said, "Does it buzz?"
He replied, "Yes, it does!"
It's a regular brute of a Bee!"
 

Here is a slightly indecent and blasphemous limerick (which is also a little rough metrically):
 

There once was a girl from Cape Cod
Who thought that all children came from God;
But it wasn't the Almighty
Who lifted her nightie,
'Twas Roger the lodger, by God!
