Check out the Zach Galifianakis Hangover Cure! This one is kind of a joke. In this video, Zach Galifianakis gives us a hangover cure, but it is really more a prevention than a cure. At Hangover School, we walk a fine line between addressing serious and joking matters. Hangover cures are not a joking matter, we take them seriously. We only provide funny videos like this so that people can forget that they are hungover. Hangovers are 80% mental.
