Steve can't attend a party because he has court side seats to the Lakers/Cavs game. Brandon places a bet on the game and watches it on TV. A shot of the televised game shows a Cavs and Lakers game on Cleveland's home floor.
Steve shows Brandon that he has 2 tickets to that night's Lakers game at the Los Angeles Forum playing the Cleveland Cavaliers. Later that evening when Brandon is watching the game on TV because he thought he placed a bet on the game, the game is being played on the Cleveland Cavaliers home court.
