One day a cowboy was riding down the trail. He came upon a fork
in the path. At the fork he looked down and found an indian
lying bucknaked on the ground with a hard-on sticking straight
up in the air. Now the cowboy was very startled by this and
gasps: WHAT THE HELL ARE YOU DOIN?!!!!
The indian sits up and says to the cowboy: this is how I tell
time,right now it is exactly 2:37 in the afternoon. the cowboy
looks at his watch and is absolutely astonished...why holy
buckin broncos son you got right on the money my watch says 2:38

Indian tells him it's an ancient indian practice and you
would'nt understand. cowboy nods his head says: much obliged but
I must be on my way, and proceeds to make his way down the trail.
a few hours later the cowboy is riding back the opposite
direction and once again comes to the fork in the path. this
time the cowboy is totally shocked at what he sees because he
looks down and see the same indian jerking off. The cowboy
says: NOW WHAT IN THE HELL ARE YOU DOIN?!!!!!!!!!! The indian
