Ventriloquist Cowboy 

A ventriloquist cowboy walks onto a ranch... 

Cowboy to Rancher:

Cowboy:  Is that your dog?
Rancher: Yup.
Cowboy:  Mind if I talk to him?
Rancher: Durn fool, don't you know dogs don't talk.
Cowboy:  So what's the harm?  May I?
Rancher: Go right ahead.

Cowboy to dog:

Dog;     Howdy.
Dog:     Hello. (Rancher's eyes pop out)
Cowboy:  Is this your master?  (pointing to the rancher)
Dog:     Yep, sure is.
Cowboy:  Does he treat you alright?
Dog:     Sure does, every day he takes me for a walk, he 
         feeds me all kinds of great food, and once a 
         week he takes me to the lake to play.


Rancher is standing there dumbfounded.

Cowboy to Rancher: 

Rancher: Is that your horse over there?
Rancher: Yes.
Cowboy:  Mind if I speak to him?
Rancher: I know the dog spoke to you, but I know for a 
         fact that horses can't talk.
Cowboy:  Well then what would it hurt?
Rancher: Go right ahead.

Cowboy to horse:
Cowboy: Hello.
Horse:     Hello.

        Rancher can't believe it.  
        He stands there with his jaw wide open.

Cowboy:  Is that your owner?
Horse:   Yup, sure is.
Cowboy:  He treat you OK?
Horse:   Sure, he rides me every day, brushes me down at 
         the end of the day, and he keeps me in the barn 
         away from the elements.
Cowboy:  Sounds good. (turns to the rancher) are those your
         sheep out here?

Rancher is beside himself:  

Rancher: Th-Th-Th-Them sheep out there, they're nuttin but 
         a bunch of liars!!
