A very old man that seems to be too good for his age. In fact, his body is extremely fit and muscular. His hair an long beard are white and he's always walking around with his pointy hat and his pipe... and that's it...
He is often completely naked from the head down, with a huge flacid penis dangling around and a couple of big testicles hanging low. He walks barefoot and seems to be completely out of reality, often talking with himself (or voices in his head).
A few moments in his presence are enough to notice that he is completely crazy
