When NASA was preparing for the Apollo expedition, they did some training on a Navajo Indian reservation. One day, a Navajo Indian and his son were herding sheep and came across the space crew. The old man, who spoke only Navajo, asked a question which his son translated: "What are these guys in the big suits doing?" A member of the crew said they were practising for their forthcoming trip to the moon, whereupon the old man became very 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 people found a tape recorder, and the old man recorded his message. They then asked the son to translate it, but he refused. So NASA took the tape to the reservation where the rest of the tribe listened and laughed but also refused to translate the elder's message to the moon. Finally, NASA called in an official government translator. He listened to the tape and reported that the moon message said: "Watch out for these guys; they have come to steal your land."
