Heartwarming / ¡Three Amigos!

• Before going to face El Guapo, Pablo asks Dusty "Can I have your watch when you are dead?". At the end, although he's alive, Dusty gives him his watch anyway.
• While he is the villain, the genuine (or at least genuine-seeming) happiness El Guapo expresses when unwrapping the sweater that his wife(?) gave to him is genuinely heartwarming, more so when he immediately drapes it over his shoulders and ties it around his neck like a small cloak. Despite the fact that they live in the deserts of Mexico (making a sweater less than useful), despite the fact that he is a ruthless villain, murderer, plunderer, rapist, and more...he is able to appreciate the gift in the spirit with which it was given.
• Nearly any scene involving Ned.
• The Amigos living out the standard Keep the Reward sequence from their films, refusing the tiny sack of pesos— which was all the money the grateful people of Santo Poco had to give. Ned proudly says the line and tosses it back to the village elder:
  "Our reward is that justice has been done!"
