Coming upon a castle, its raining and would be nice to have some roof over your heads.

The knights are welcomed into the hall, and introduced to the many knights of this castle:
Sir Pent, Sir Cular, Sir Vix, Sir Vant, Sir Tain and Sir Plus.

Everything goes fine aslong as a stiff upper lip is maintained and the rules of honor and hospitality are upheld, any exclamations along the line of "this castle is full of joke knights" results in instant challenges to the death. They may have funny names, but their skills arent lacking.

I have actually used Sir Pent in a game. He started out as a rival, but was quite honourable. The players never trusted him, for some reason.
I also had a Baron Plaine.

We've now got a Sir Lee...

Don't forget those Looney Tunes classics, Sir Loin of Beef and Sir Rhosis of the Liver.

My best up to now is Sir Edward of Norton... ancestor of a famous actor.
