My friend, and teammate, Mark was telling my wife one-day what it takes to win a mountain bike race.  He said to her, forgetting for a moment that he was conversing with a member of the opposite sex, "you need TITS to win." My wife said "What!"  Only at that moment did Mark realize what he had just said and with a very embarrassed look on his face he explained that what he meant was you need Time In The Saddle to win.
