That phrase, 'might as well be', isn't used all that often, but it always seemed a little odd to me. Sometime during my younger teen years, that phrase struck me funny and I turned it into the name of my Dungeons and Dragons paladin character--Midas Welby.
Many years later, when I decided to write a fantasy novel, I turned that old D&D character into the protagonist of my story The Shard. I mean, he might as well be the main character, right? Rather than a paladin, I made him a minor nobleman, who had been born to a fisherman but gained notice during his service fighting barbarians and became a captain-of-the-guard for a major noble, who later knighted him, married him to his daughter, and granted him a small keep.
I guess I was very subtle about his name in the book, because it was published in 2015 and not one reader has ever noticed that his name was a play on that phrase.
