Gethard tells stories of hitting rock bottom in his new one-man off-Broadway show, ‘Career Suicide,’ which is billed as a comedy about "suicide, depression, alcoholism and all the other funniest parts of life." The host of the CNN series 'Parts Unknown' talks about what food sends him into a "spiral of depression," the perils of cooking bacon naked, and how he fell in love with Vietnam. His new cookbook, 'Appetites,' features recipes he cooks at home for his daughter.
