The Wise Dog

A man walks into a bar with his dog and orders two glasses of whiskey.

He proposes a toast and both he and his dog empty their glasses.

The girl behind the bar is surprised and asks, Can your dog perform other tricks?"

"But of course", the man answers, "he can even satisfy a woman."

Anxious to know more the girl leads the man and the dog into a little room above the bar. She undresses and full of expectation, she lies down on the bed. The dogs looks at her and does nothing.

"It's always the same thing with you!", the man then shouts to the dog, 'I'll show you how to do it one last time.'
