Two guys are riding to work on the bus. They both see two dogs goin at it on a lawn. One guy, whos married, looks at the other and says, Geez, Id give anything to do it to my wife like that.

The other, a single guy, says, Heck, thats easy. Just feed her three martinis.

The same two guys are riding the bus to work the next morning. The single one asks the other, Well, did you get to do it to your wife doggie style?

The married guy replies, Yes, but it took SIX martinis.

The single guy exclaims, SIX martinis! How come so many?

The husband replies, Hell, it took three just to get her out on the lawn.
