I remember in Revenge of the Sith, when the actor playing Vader yells "nooooooooo", at what is supposed to be the emotional climax of the trilogy, the theater roared in laughter.
In Star Wars: The Last Jedi. The scene where Leia gets blown out of the spaceship. She floats there a little then opens her eyes and proceeds to use the Force to fly through space towards the ship.
The audience absolutely erupted in laughter at that.
