Other astronauts caused months of fretting. One, a cheerfully uninhibited fellow who used four-letter words as grace notes to his everyday conversation, was a special project. Look, they finally told him, hum instead of talking. (Another version of the story is that NASA actually sent him to a psychologist, who hypnotized him and left him with the posthypnotic suggestion: Hum.) That’s why, in the tapes of his mission, one Apollo astronaut can be heard going “dum-te-dum-te-dum-te-dum” as he bounces across the lunar surface.]
