Arrows

All of the members of the tribe are expert archers.
Except one.
No matter how much he practices, he misses. Or he breaks the string on his bow.
He falls off of his horse a lot.
Don’t stand behind him when he’s got his tomahawk. His grip’s much too loose.
When asked to scalp an enemy, he merely takes a little bit off of the top and gives an excellent shave.
In fact, he’s got a business on the side. A barber shop in the white man’s settlement.
As for the gambling tables in back, well, that’ll never catch on.
