Neil Armstrong's first words when he landed on the moon 35 years ago today were "Good luck, Mrs Smith." When he got back he was interogated as to what they mean, but he refused to say.
The story was then revealed when "Mrs Smith" died.
When Neil was a kid, he lived next door to Mr and Mrs Smith. When Mr Smith asked Mrs Smith for oral sex, Mrs Smith stated "I'll give you head, when the boy next door walks on the moon"
N.B. This story was told in Neil Armstrong's biography
