In college, I lived in a dorm with community bathrooms, and evidently some of my neighbors had been remiss in their flushing duties, because this cloying bit of verse appeared on the bathroom wall:
There was once a man so clever,
He made a little lever,
That when you pulled down
It made such a sound!
And your toilet was clean forever.
As sympathetic as I was to the cause, I couldn't let something so sappy go by without comment. So I got on the computer and produced a 'sequel' in the same font & everything:
That lad so dapper,
His name: Thomas Crapper.
We revere him in a curious way;
When one empties his bowels
The bowl he befouls
Still bears Tom's name to this day.
