This is Sean's pudgy left hand. Today I heard him referring to his ring finger as Brother. I then found out he has his own names for the different fingers.
From right, what we call the thumb he calls Fatty, well, "that's the fattest one", so nothing strange there. Next comes Poker "cos it's used to poke anyone", especially Mr Tortoise. In the middle is Tower "cos it's the tallest one". Next comes Brother and I'll tell you why later. The last one, he said is, "Pinky or you can call it Baby." So why Brother? Sean said, "Because it's next to the Pinky, and the Brother takes care of the Pinky."
