The year is 2258 and Mike and Maureen land on Mars after accumulating enough frequent flier miles.
They meet a Martian couple and start talking about all sorts of things. Mike asks if Mars has a stock market, if they have laptop computers, how they make money, etc. Maureen discusses hobbies, cuisine on Mars etc.
Finally, Maureen brings up the subject of s.x.
“Just how do you guys do it?” asks Maureen.
“Pretty much the same way you do,” responds the Martian woman.
Discussion ensues and finally curiosity gets the better of them and the couples decide to swap partners for the night and experience one another. Maureen and the male Martian go off to a bedroom where the Martian strips.
He’s got only a teeny, weeny member – about half an inch long and just a quarter inch thick.
“I don’t think this is going to work,” says Maureen understandably.
“Why?” he asks, “What’s the matter?”
“Well,” she replies, “It’s just not long enough to reach me!”
“No problem,” he says, and proceeds to slap his forehead with his palm.
