The crowd goes wild, confetti falls from above, white doves are released into the open, Animal Collective launches into "My Girls." You can't just make this stuff up. After three preliminary rounds, the showdown between red vs. black reaches its peak tonight, where finalists play on a massive custom-made Connect Four board, the way god intended.
