As a child I didn't understand why there are scenes of people punching/slamming through a wall in so many movies, it's horribly unrealistic. I only learned later that no, homes in the US have walls out of cardboard. Interesting choice for a country plagued by tornadoes.
@Amikke To be fair, we only started making them out of cardboard after we stopped making them with asbestos. Older buildings here still have the stronger cancery ones.
