It involves a ventriloquist biker (I dont know why a biker but there you go).
He pulls up at a farm where the farmer is sitting on his front porch,
drinking beer in the fading light of a sunset:

Biker: Hey, cool dog. Mind if I speak to him?
Farmer: This dog don't talk!
Biker: Hey dog, how's it going?
Dog: Doin alright
Farmer: (Extreme look of shock)
Biker: Is this your owner? (pointing at farmer)
Dog: Yep.
Biker: How's 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.
Farmer: (Look of disbelief)
Biker: Mind if I talk to your horse?
Farmer: Horses don't talk!
Biker: Hey horse, how's it goin?
Horse: Cool.
Farmer: (an even wilder look of shock)
Biker: Is this your owner? (pointing at farmer)
Horse: Yep.
Biker: How's he treat 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.
Farmer: (total look of amazement)
Biker: Mind if I talk to your SHEEP?
Farmer: Them sheep ain't nothin but liars!!!
