Australian Ninja Warrior 2
On Australian Ninja Warrior 2, Lee shockingly fell on just the second obstacle in his heat (Heat 6), which was the Bungee Slider to Bullet. However, due to the fact that only 17 competitors could complete the obstacle, there were 3 competitors who failed on the obstacle and still advanced to the semifinals, including him. In his semifinal (Semifinal 4), he went out on just the third obstacle (the Broken Pipes).
