The Movie Theater

Film and Movie have been in a contentious sibling rivalry for longer than anyone can remember. This rivalry comes to a head every night, and they spark and clash with so much intensity that light shoots up and through all of the bulbs on the marquee. That's why cinemas are so blazingly bright on the outside and pitch black on the inside, because they're one big fight. That also explains why they serve popcorn, since it gets heated and explodes.
