"Space Exploration at Its Best!" joke
In the future, man is exploring the universe. Due to the excessive cost, they can only send out small teams of explorers to search and investigate the millions of planets they come across. One such team lands on a barren planet that seems to be just one big rock. As they investigate, their sensors pick up life signs. They follow the sensor until they come up on a large stone sentinel (guard) crouched down with its arms around its legs. They can detect life signs from it, but it doesn't move, doesn't appear to breathe.
They call back to their commanders on Earth and report this abnormal situation. Because of this, many great scientific minds, military generals, politicians, and technical wizards are sent to try to interact with this leviathan. After many months, every walk of life has come to try to communicate with the sentinel, but nothing happens. It just sits there with its arms around its legs.
Finally, one of the teamsters who sets up the stage occasionally when some big-shot dignitary comes thinking he can do better than the smartest people in the galaxy. He turns to the sentinel and in frustration yells, "Will this thing EVER communicate with us?!?!?!"
Suddenly the sound of stone grinding against stone starts, and the great stone sentinel stands up. It scratches its chin pensively, then blurts out, "No." It then crouches down again and assumes the same position it was in before.
Another teamster who saw this turns to the man who yelled at the sentinel originally and says, "Well, it only stands to reason."
