The first fourteen lines of Hudibras by Samuel Butler
illustrate the verse form:

When civil dudgeon first grew high,
And men fell out they knew not why;
When hard words, jealousies, and fears,
Set folks together by the ears,
And made them fight, like mad or drunk,
For Dame Religion, as for punk;
Whose honesty they all durst swear for,
Though not a man of them knew wherefore:
When Gospel-Trumpeter, surrounded
With long-ear'd rout, to battle sounded,
And pulpit, drum ecclesiastick,
Was beat with fist, instead of a stick;
Then did Sir Knight abandon dwelling,
And out he rode a colonelling.
