Here is an old one but one of my all time favorites.

There's this cowboy who has been practicing being a ventriloquist. One late afternoon, while crossing a rough section of open country he comes across an Indian with a flock of sheep. He pulls up to the Indians small little campfire, dismounts and says "Howdy. Do you mind if I share your fire and bed down for the night?"

The Indian grunts and nods his head. After cooking his dinner and drinking his coffee and being unable to get the Indian into a conversation he decides to have some fun with him. Looking over at the Indians dog he asks "He treating you alright?"

Throwing his voice he makes it sound like the dog answers him, "He's OK, feeds me all his scraps. Let's me lick the bacon grease off the pan. Yeah, he treats me good."

The cowboy nods as the Indian looks amazed. Then the cowboy looks across the fire to the horse. "How about you buddy? Does he treat you good?"

Again, throwing his voice he makes it sound like the horse answers. "Sure! He doesn't ride me too hard, always brushes me down at the end of the ride. He makes sure I have good grass to graze and sweet water to drink."

Now the Indian is looking on in amazement. So the cowboy goes over to where the sheep are standing. Before he can say anything the Indian says "Sheep lie!"
