There was an Old Man who supposed
That the street door was partially closed;
   But some very large rats
   Ate his coats and his hats,
While that futile Old Gentleman dozed.

It needn't have ribaldry's taint
Or strive to make everyone faint
       There's a type that's demure
       And perfectly pure
Though it helps quite a lot if it ain't.
                 
                        Don Marquis



The limerick packs laughs anatomical
Into space that is quite economical
       But the good ones I've seen
       So seldom are clean
And the clean ones so seldom are comical.

There was a young man named Cass
Took his girl for a sail on Lake Bass
       He thought her quite handsome
       So screwed her on the transom
Thus propelling the boat with his ass.

On a maiden a man once begat
Bouncing triplets named Nat, Tat and Pat
       'Twas fun in the breeding
       But hell in the feeding
She hadn't a spare tit for Tat

There was a young parson named Bings
Who talked about God and such things;
       But his secret desire
       Was a boy in the choir
With a bottom like jelly on springs.
