So, these two guys are car pooling home from work one day. Traffic is barely crawling along and they are both a bit bored.

So the driver is looking around and suddenly he 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, being a man of the world, 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 has never had sex doggie style.

So the passenger says, "You have to try it. Its pretty cool. Here's what you do. Tonight when you get home, fix your wife a margarita 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?"

The driver replies, "It was great. But it took me 6 Margaritas just to get her on the front lawn."
