|Undefeated Galactic Champion in the game 'Spock, Paper Scissors'|
For was it not he who told us the famous Vulcan idiom: "Only Nixon could go to China"?
But that is not the end of Spock's erudite turn of phrase. Other sayings which have been heard throughout the series include:
"Only a Romulan breaks wind in a revolving door"
"A bird in the hand in worth two in the reverse-polarity plasma phase array"
"A Klingon's honour isn't worth a second-hand snot rag"
"Logic dictates that one of us in this room is a liar, am I'm not wearing frilly panties"*
"Your mum's so fat, she's in orbit around Ceti Alpha IV"
"YEAH, YOUR MUM"
Wise words, indeed.
* Saying does not work if you are wearing frilly panties.
