Who says American Indians don't have a sense of humor?

Here's one to kick it off -- admittedly, and oldie but a goodie:
When NASA was preparing for the Apollo project, they did some astronaut training on a Navajo Indian reservation. One day, a Navajo elder and his son were herding sheep and came across the space crew. The old man, who only spoke Navajo, asked a question, which the son translated: "What are the guys in the big suits doing?" A member of the crew said they were practicing for their trip to the moon.
The old man got really excited and asked if he could send a message to the moon with the astronauts. Recognizing a promotional opportunity for the spin-doctors, the NASA folks found a tape recorder. After the old man recorded his message, they asked the son to translate. He refused. So the NASA reps brought the tape to the reservation, where the rest of the tribe listened and laughed, but refused to translate the elder's message to the moon.
Finally, NASA called in an official government translator. He reported that the moon message said: "Watch out for these guys; they've come to steal your land."
