Here's a couple limericks my dad taught me near 60 years ago. They were probably already old at the time.

There was a young man from Boston
Who bought himself an Austin (very small motorcar)
There was room for his ass
And a gallon of gas
But his balls hung out and he lost 'em

There was an old lady from Wheeling
Who had a peculiar feeling
She laid on her back
And let out a crack
And pissed all over the ceiling
