A guy walks into a bar, hits sits down at the bar and orders a beer, he can see back into the kitchen area in the back. Laying by the back door is a me dog licking himself down there, this dog was going to town and the guy just keeps drinking his beer, when he was finished, he ordered another beer and when the bartender brought his drink to him , he pointed at the dog and said , man I wish I could do that, and the bartender says to him well you may want to introduce yourself to him first. :)
