Ever tried doggy style?

Two guys were sharing a car home from work one day. Traffic was crawling along and they are both a bit bored. The driver, looking around suddenly points at two dogs having sex in someone's front lawn.

"Look", he shouts "What are the those dogs doing? Are they fighting?"

The passenger, surprised at his colleague naivety, replies "They are having sex. Don't tell me that you have never had sex doggie style before?".

The driver, a bit embarrassed, admits that he never has.

So the passenger says "You have to try it. It's really good. Here's what you do. Tonight when you get home, get your wife a large gin and tonic and then suggest that you want to try this new sexual position."

The driver thinks a bit and then decides he will give it a try.

So the next morning, the two commuters are back in the car and the passenger asks "Well. How did it go?"

To which the driver replies "It was great; but it took me six gin and tonics just to get her naked in the front lawn."
