Neil Armstrong is quoted to have said- "Good luck Mr. Gorsky" when he was on the moon, but no one knew what it meant, and Neil refused to say.
And then, years later, when Mr. Gorsky was dead, Neil Armstrong admitted that he'd overheard an argument between Mr and Mrs. Gorsky that went "Oral sex! You want oral sex?! You'll get oral sex when the kid next door walks on the moon!".
"True story"?- um, no actually.
It's an Urban Legend. The transcript of Apollo 11 is on the web, and Mr Gorsky never appears anywhere. It was actually invented by a comedian Buddy Hackett, and was first performed in front of Neil Armstrong who seemed to find it pretty funny.
Then again, the guy sitting next to you probably doesn't know that it's an Urban Legend...
