Recently my home sewer needed to be replaced, and I struck a deal with the plumber. He had a blob on his arm, a pathetic attempt made years ago to cover up an ex-wife's name, and I suggested that he deserved better. It took a little convincing to have him go for the plumber's wrenches in the claws, but after his crew saw the concept drawing their enthusiasm was unanimous... and now, after two sessions, the cover-up is complete and the occupationally enthusiastic tattoo is a source of pride for him.
