AP-More than a half-million fans celebrated the Los Angeles Lakers' second straight NBA championship Monday as Shaquille O'Neal and Kobe Bryant promised to do it all again next season. ''Three-peat, three-peat, three-peat,'' O'Neal exhorted a purple-and-gold throng massed outside Staples Center in a rousing hip-hop performance that capped the festivities.  

Bryant put it another way: ''We're going to get another one next year, again --- back to back to back.''
