Movie lines people laughed at in theaters despite not actually being intended to be funny?
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.
It's bad, but is it as bad as in movies/tv where people look into a microscope and see little viruses multiplying, or even worse, DNA double-helices floating around? Maybe it is...
