Doc No Scars

"I think you can guess why you are here," Doc said. Monk rubbed his hairy hands together. Of the six men present, Monk's skin alone bore scars. The skin of the others held no marks of their adventurous past, thanks to Doc's uncanny skill in causing wounds to heal without leaving scars.

But not Monk. His tough, rusty iron hide was so marked with gray scars that it looked as if a flock of chickens with gray-chalk feet had paraded on him. This was because Monk refused to let Doc treat him. Monk gloried in his tough looks.
