Culhwch the Bluffing

I could not believe that I stood there blushing in front of my stepmother. I had just met her and already she was proposing that I marry her daughter. I said the first thing that came to my mind: “I am not yet old enough to marry.” Stupid and insolent as always, I had tried to bluff my way out, but she beat me at my own game. She cursed me to win a giant’s daughter— I now fully understand why my own mother tried so hard to prevent my father from ever remarrying: stepmothers truly are wicked.
My father called me out on my own bluff and asked why I was so stupidly blushing. After offering my explanation, father reminded me of my salvation—“Arthur is your first cousin.”
King Arthur, my first cousin, is the most fantastic, powerful man to ever live, and though I personally could never win a giant’s daughter, I knew I could stick to my old trick, bluffing, and he would win the girl for me.
My good-looks got me through the front gate, and with a little more bluffing, I got exactly what I came for: Arthur's help. I knew that he and his knights would take care of getting me the girl.
Arguably, the most difficult part of my quest was standing before Ysbaddaden Chief Giant and listening to his list of demands. He asked me to do some crazy farming, and I said the first thing that came to mind: “it's easy for me to manage that, though you think it's not easy.” Fake-it-till-you-make. I repeated that phrase 39 times as he droned one with ridiculous demand after ridiculous demand. I couldn't think of anything else to say. But I knew Arthur would come through, and he did. I got the girl. Turns out I never fooled the old giant. My bluff was called again when he told me, “but you don't have to thank me for that. Instead thank Arthur, the man that made this happen for you.”
Thanks Arthur.
