Prince Valiant and . . . ?

I saw this in the newspaper and knew I’d just have to blog it. This is really, truly from the Prince Valiant comic. It says it’s Sir Gawain in disguise, but you can judge for yourself.

I think the word bubble should say, “My name is Inigo Montoya. You killed my father. Now prepare to die!”

Prince Valiant + Princess Bride = Twue Wove? What will Westley say?
