An Old Man of the Dee - Vintage Edward Lear Limerick

There was an Old Man of the Dee,
Who was sadly annoyed by a Flea;
When he said, "I will scratch it!"
They gave him a hatchet,
Which grieved that Old Man of the Dee.

A Fly And A Flea In A Flue - Ogden Nash Classic Limerick

Were imprisoned, but what could they do?

Said the flea, "Let us fly!"
And they flew through a flaw in the flue.
