"Ventriloquist Laugh" joke

A ventriloquist walks into a small Australian town and sees a local sitting on his porch patting his dog and figures he'll have a little fun.
Ventriloquist: 'G'day mate. Good looking dog... mind if l speak to him?'
Local: 'The dog doesn't talk, you stupid man.'
Ventriloquist: 'Hey dog, how's it going old mate?'
Dog: 'Doin' all right.'
Local: (Look of extreme shock)
Ventriloquist (pointing at local): 'Is this man your owner?'
Dog: 'Yep.'
Ventriloquist: 'How does he treat you?'
Dog: 'Real good. He walks me twice a day, feeds me great food and lakes me to the river once a week to play.'
Local: (Look of utter disbelief)
Ventriloquist: 'Mind if I talk to your horse?'
Local: 'Uh, the horse doesn't talk either... I think.'
Ventriloquist: 'Hey horse, how's it going?'
Horse: 'Cool.'
Local: (Absolutely dumbfounded)
Ventriloquist (pointing at local): 'Is this your owner?'
Horse: 'Yep.'
Ventriloquist: 'How does 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.'
Local: (Total look of amazement)
Ventriloquist: ‘Mind if l talk to your sheep?'
Local: 'The sheep's a bloody liar!'
