NEW YORK ( TheStreet) -- "It's time to stop worrying and love the bull," Jim Cramer told the viewers of his "Mad Money" TV show Tuesday. He said that ever since the market bottom in March in 2009, worrying has been just plain wrong. "The time to worry was last year," he said, "but now it's time to buy." Cramer said the bears still seem to have an endless stream of things they're worried about, whether its Apple's ( AAPL) iPad sales, Treasury auctions, Federal Reserve statements, or a pending collapse in commercial real estate. Cramer said all of these worries just don't matter.
