Hall Sex

Three guys were standing around the golf course talking about how often they have sex with their wives.
The first guys says, "I'm lucky if I get sex once a month. and if we do its just regular old missionary style sex." The other two guys shake their heads in understanding.
The second guy says, "I get to have sex with my wife a couple of times a month and she lets me do it missionary and doggie style." The other two guys again shake their heads in understanding.
The third guy says, "me and my wife have sex every day." His two buddies look at him in amazement and one of them asks, "What kind of sex do yall have?" The guys looks at him and says, "We have hall sex."
His buddies look at him and one says, "Hall sex? I've never heard of that."
The guy looks at him and says, "When we pass each other in the hall we look at each other and say, 'Fuck You'."
