A verse I heard sung in O'Donoghues in the sixties goes:

"There's a moral to me story, a lesson for to learn
If ye want a mot get one of your own, don't chase the Twangman's hen
Or you'll end up like the poor oul bags, in a plot in Mount Jerome
And your no bloody use to anybody, when the maggots is chewin' your bones"
Don't know who put it together, but it works well as an alternative final verse or even a 5th one.
