Since lottery jackpots are traditionally shared among everyone who picked the winning combination, the only skill/logic in picking a number is picking one that you believe is an uncommon choice. That way, should you win, there's less people to share it with. And there probably is statistical evidence to back up the the idea that some numbers are chosen by people more often than others (ie: somehow everyone's lucky number is 7).
