Passwords
One of the best ways that Tony Stark’s character makes his mark through the films is with his irreverent humor. His confidence in his own genius means that he takes everything in his stride, even blonde ripped Gods with giant hammers and power over the weather.
His teasing of Thor is one of my favorite things to look out for in the movies, and Thor often doesn’t notice he is the butt of Stark’s jokes. During Thor: Ragnarok, Thor is attempting to escape in a Quinjet but needs a password to open the ship. In a nod back to the original Avengers film, Thor realizes that the password Stark has programmed is Pointbreak, his joke about how Thor looks like Patrick Swayze in that film.
