While riding one day, a cowboy met an Indian riding along with a dog and a sheep. He began a conversation:

Cowboy: "Hey, cool dog you got there. Mind if I speak to him?"

Indian: "Dog no talk."

Cowboy: "Hey dog, how's it going?"

Dog: "Doin' all right."

Indian: Look of shock.

Cowboy: "Is this Indian your owner?" pointing at the Indian.

Dog: "Yep"

Cowboy: "How does he treat 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 total 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 the Indian.

Horse: "Yep"

Cowboy: "How's he treat you?"

Horse: "Pretty good, thanks for asking. He rides me regularly, brushes me down often, and keeps me in a shed to protect me."

Indian: Total look of utter amazement.

Cowboy: "Mind if I talk to your sheep?"

Indian: "Sheep liar."

Was the indian wearing rubber boots?
