I refuse to shoot a defenseless man! (Opponent, who is a woman, is lying on the ground without any bullets, one shot away from death. Good cowboy shoots all five remaining shots in the air.)
Later...
(Situation exactly reversed.) Please! Mercy! You wouldn't shoot a defenseless man, would you?! (Lady:) Of course I wouldn't. (Shoots him.) He'll never know.
BUG: You can defy the law of conservation of momentum with airskipping: angling the craft down as far as possible (after you reach the goal) until the "PULL UP" warning comes on and then quickly pulling back up will give you a moderate boost, and it is possible to repeat the process BEFORE you fall back down to where you were before, enabling you to airskip indefinitely and get tens of thousands of extra feet out of your trip.
Continue the game and beat the king for 1 more time :)
