On a hot summer day, a country bumpkin came into town with his dog. He tied the dog under the shade of a tree and went into a bar for a cold beer.
About twenty minutes later, a policeman entered the bar and asked who owned the dog tied under the tree. The bumpkin claimed it was his. The policeman said, "Your dog seems to be in heat."
The bumpkin replied, "No way dog's in heat... she's cool 'cause I got 'er tied under the shade tree."
The policeman said, "No! You don't understand. Your dog needs to be bred."
"No way," the bumpkin said. "Dog don't need bread, she ain't hungry, 'cause I fed 'er beef jerky this mornin'."
Now the policeman got mad and yelled out, "NO! You don't seem to understand. Your dog wants to have sex!"
The bumpkin looked at him with a long pause and said,
"Go ahead. I always wanted a police dog."
