Remember this kid, Daniel, from
Deanna's Show in Dusseldorf ? (Scroll down)
He had me draw on his leg, he was fairly drunk, and was going to tattoo it in soon after.
I advised against it because a blunt sharpie marker on a drunken leg is not the best of conditions for something you will have for life.
Well, he did it. Complete with sect holding a beer can just like I drew it.
