Does there really need to be a reason for Conan O'Brien and Steven Yeun to go for a session at a Los Angeles Korean Health Spa? No. The pair went through what can only be described as the closest thing to legal torture, being scrubbed to ribbons and basically boiled in their own skin. Yeun even admitted that he'd far sooner face a zombie apocalypse than a lifetime of these Korean 'treats'. Seriously though, why would anybody go through with these practices and actually pay money for the pleasure (horror)?
