A MARRIED COUPLE and a single guy are stranded on a deserted island.
Every day the single guy climbs up a coconut tree to watch for ships.
Every time he climbs up the tree, he shouts down, “Hey, you guys stop screwing down there.”
Every time he says that, the married guy says, “We”re not doing anything, we’re just sitting here.” To which the single guy up the tree replies, “Well, from up here it sure looks like you're screwing.”
Days go by with the same routine.
Then one day the single guy says he's tired and that the married guy should go up the tree.
The married guy goes up the tree and looks down and says, “You’re right, from up here it DOES look like you’re screwing down there."
