When Apollo Mission Astronaut Neil Armstrong first walked on the moon, he not only gave his famous "One Small Step for Man, One Giant Leap for Mankind" statement, but followed it by several remarks - usual com traffic between him, the other astronauts and Mission Control. Before he re-entered the lander, he made the enigmatic remark "Good luck, Mr. Gorsky."
Many people at NASA thought it was a casual remark concerning some rival Soviet Cosmonaut; however, upon checking, there was no Gorsky in either the Russian nor American space programs.
Over the years, many people have questioned him as to what the "Good luck, Mr. Gorsky" statement meant. On July 5, in Tampa Bay, FL, while answering questions following a speech, a reporter brought up the 26 year old question to Armstrong.
He finally responded.
It seems that Mr. Gorsky had died and so Armstrong felt he could answer the question.
When he was a kid, Neil was playing baseball with his brother in the backyard. His brother hit a fly ball which landed in front of his neighbors' bedroom window. The neighbors were Mr. and Mrs. Gorksy.
As he leaned down to pick up the ball, he heard Mrs. Gorsky shouting at Mr. Gorsky, "Oral sex? Oral sex you want? You'll get oral sex when the kid next door walks on the moon!"
Addendum: This is an nice Urban Legend, but unfortunately it is an not true. See NASAs reaction to it.
