A friend of mine tells a great story of being on a ship involved in the tourist sub dives to the titanic and one night in the bar a few guys were trying to out do each other with tales of their exploits..."1972 yeah that was the year i walked to the north pole" "1972 i walked to the north pole and flew to the south pole" etc etc. After a bit of this they turned to a guy at the bar quietly drinking his beer and said "so what did you do in 1972" There was a pause and the man relpied "1972..oh yeah that was the year i went to the moon.." and went back to drinking his beer.
Turned out he was actually one of the apollo astronauts.
