I think the question was more about songs like:
There once was a farmer who took a young miss
In back of the barn where he gave her a -- lecture
On horses and chickens and eggs
And told her that she had such beautiful -- manners
That suited a girl of her charms
A girl that he'd like to take in his -- washing
And ironing and then if she did
They could get married and raise lots of -- Sweet Violets.
