indispensible (I think in life, you don't always get to choose the cards you are dealt. And if you try to get another hand, it's sort of cheating. I am honoured to be dealt the hand of Leonardo da Vinci, but please spare me the horror of being dealt his ear also. When it comes to bluffing, my beard does come in somewhat handy, as I'm able to hide my disgust at the mailing of body parts, and instead, keep a stony eye on my opponents, with which to deter them.)
