How do I beat Rottingham in a sword fight?

Hint 1 of 4:

The rules are basically the same as in other fights -- you win by giving
proper (thus rhyming) responses.  But you are never able to go on the attack
yourself.

Hint 2 of 4:

Also, the insults change, but the responses do not.  You just need to do some
thinking to match the insults Rottingham gives you with what you've already
learned.

Hint 3 of 4:

If you can't figure out a suitable response, it may just be that you haven't
encountered the full range of insults from other pirates.  There are a total
of 16 insult and response combinations that I was able to find.
