One guy, who's married, looks at the other and says, "Jeez, I'd give anything to do it to my wife like that."

The other, a single guy, says, "Heck, that's easy. Just feed her three beers."

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 beers."

The single guy exclaims, "Six beers! How come so many?"

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