Hello Bill - I've read them all and this one's not in it:

There was a young chap from Cape Horn
Who wished that he'd never been born
And he wouldn't have been
If his mother had seen
That the end of the rubber was torn.

and one more, the best I've got because it's legally sound:

There was a young lawyer named Rex
Who had a small organ of sex
When arraigned for exposure
He said, with composure
"De minimus not curat lex"

(the law does not concern itself with small things): a reasonable defence, surely
