General note: a limerick is rhyme scheme AABBA. The lines 1, 2, and 5 have 3 metrical feet (da DA da da DA da da DA). The lines 3 and 4 have only two metrical feet (da DA da da DA).
The classic example:
There was an old man from The Heath
Who sat on a pair of false teeth
He jumped up with a start,
And said, “Oh bless my heart,
I’ve bitten myself underneath!”
If you didn’t waste your childhood reading silly books of baudy limericks, then fer gosh sakes, what did you do for fun?
I always use this one for comparison to make sure I’ve got it right…
There once was a young girl named Alice
Who chose dynamite for use as a phallus
'Cept when she lit a match
They found half of her snatch
In Ft. Worth… and the rest in Dallas
Working Too Hard
A mathematician went crazy
His calculations became a bit hazy
He did all his sums
COunting on his thumbs
Two Coats
I bought some invisible paint
Offensive and gaudy, it ain’t
I can’t find my house
And I can’t find my spouse
