When's the last time the Chicago White Sox won a World Series?

The Chicago Cubs are the crosstown rivals of the White Sox, a rivalry that some made fun of prior to the Sox's 2005 title due to the fact that both of them had extremely long championship droughts. The nature of the rivalry is unique; with the exception of the 1906 World Series, in which the White Sox upset the favored Cubs, the teams never met in an official game until 1997, when interleague play was introduced. In the intervening time, the two teams sometimes met for exhibition games. An example of this volatile rivalry is the game played between the White Sox and the Cubs at U.S. Cellular Field on May 20, 2006. White Sox catcher A.J. Pierzynski was running home on a sacrifice fly by centerfielder Brian Anderson and smashed into Cubs catcher Michael Barrett, who was blocking home plate. Pierzynski lost his helmet in the collision, and slapped the plate as he rose. Barrett, who apparently believed Pierzynski was going to fight him, stopped him and, after exchanging a few words, punched Pierzynski in the face, causing a melee to ensue. Brian Anderson and Cubs first baseman John Mabry got involved in a separate confrontation, although it was later determined that Mabry was attempting to be a peacemaker. After ten minutes of conferring following the fight, the umpires ejected Pierzynski, Barrett, Anderson, and Mabry. As Pierzynski entered his dugout, he pumped his arms, causing the soldout crowd at U.S. Cellular Field to erupt in cheers. When play resumed, White Sox second baseman Tadahito Iguchi blasted a grand slam to put the White Sox up 5-0 on their way to a 7-0 win over their crosstown rivals. While there are other major league cities and metropolitan areas in which two teams co-exist, all of the others feature at least one team which began playing there in 1961 or later, whereas the Sox and Cubs have been competing for their city's fans since 1901. Only in New York, where the Yankees and Mets compete is there a comparable intra-city rivalry.
