A further reference to Woo comes during the bar shoot-out scene where both Danny and Nicholas jump in the air firing two guns. This action is known as Yi dan qun ying, and can be seen at its most glorious in Hard Boiled, where Chow Yun-Fats Tequila offers a similarly athletic display. It must also be noted that the bullet time jump is a direct answer to Dannys earlier question of have you ever shot two guns while jumping through the air. The toothpick can also be seen as a nod to Tequilas similar tic in the same film.
