I forgot that #ClarkGriswold was a... Chemist? Or nutritional engineer or food scientist or something? He works on some additive that keeps cereal crunchy and a super-sleek cooking oil that he uses to go sledding. This kooky, horny, occasionally sociopathic guy... Is a scientific scholar? Or did I miss a part because last time I saw this movie I thought it said somewhere he was in marketing? #ChristmasVacation #nationallampoonschristmasvacation
