Every time an Indian walks into the chief’s teepee he sees
the chief masturbating. They finally realize this is a
serious problem, so they fix him up with a nice woman, and
she starts living with him in his teepee.

One day, one of the Indians walks into to chief’s teepee and
there’s the chief masturbating again.

He says, “Chief, what are you doing? We fix you up with a
beautiful woman.”

The chief says, “Her arm get tired.”
