One hot summer day, Albert came to town with his dog, tied it under the shade of a tree, and headed into the pub for a cold one..
Twenty minutes later, a cop entered the bar and asked, "Who owns the dog tied under that tree outside?"
Albert called out, " It's mine, bloke."
"Your dog seems to be in heat" the cop said.
Albert replied, "No way. She's cool as, 'cause she's tied up under that shade tree."
The cop said, "No! You don't understand. Your dog needs to be bred."
"No way," said Albert. "That dog don't need no bread. She ain't hungry 'cause I fed 'er this mornin'."
The exasperated cop said, "NO! You don't understand; your dog wants to have sex!"
Albert looked at the cop and said, "Well, go ahead. I always wanted a police dog..."
