Three Amigos/Fridge

Fridge Brilliance

 * Three Amigos - Notice how we keep seeing the same three Amigos running around during the climax, but when the villagers all appear, their uniforms look far less detailed and, well, they're not played by the three leads? That's because to the confused banditos, they all looked like the real amigos, and we see what they're seeing during the gunfight.
