"The Ventriloquist Cowboy" joke

A ventriloquist cowboy walks into town and sees an Indian sitting near his pad.
Cowboy: Hey, cool dog. Mind if I speak to him?
Indian: Dog no talk.
Cowboy: Hey dog, how's it going?
Dog: Doin' all right.
Indian: [Extreme look of shock]
Cowboy: Is this your owner? [pointing at Indian]
Dog: Yep
Cowboy: How's he treating you?
Dog: Real good. He walks me twice a day, feeds me great food, and takes me to the lake once a week to play.
Indian: [look of disbelief]
Cowboy: Mind if I talk to your horse?
Indian: Horse no talk.
Cowboy: Hey horse, how's it going?
Horse: Cool.
Indian: [extreme look of shock]
Cowboy: Is this your owner? [pointing at Indian]
Horse: Yep
Cowboy: How's he treating you?
Horse: Pretty good, thanks for asking. He rides me regularly, brushes me down often, and keeps me in the barn to protect me from the elements.
Indian: [total look of amazement]
Cowboy: Mind if I talk to your sheep?
Indian: Sheep lie!
