Stock Market

According to this article on CNN Money there is a saying on Wall Street "sell in May and walk away" in regard to the next six months of the calandar year. Is this for real? Am I really suppose to dump everything because it is spring? If so what the hell do I do with the money? If I put it my checking account I know I will end up pissing it away and end up needing a loan in November to get back into the game. What does everybody else do?
