Some things in life will always be true: Chocolate is better than vanilla, the Cubs will never win a World Series, and people falling is funny. Lucky for us, fashion shows around the world ask the impossible from the models who are displaying a designer's creations: to walk at a fast pace wearing insanely constructed shoes and clothing that is sometimes designed to trip the wearer up. What this means is a bunch of models taking a tumble on runways around the world. And don't feel guilty about laughing, because all the models who took a spill are all okay.
