Employee jokingly tells boss he has a disease, gets fired the next day - could this be wrongful termination?

A workplace dispute shared online has gained attention after an employee was fired because of a misunderstood joke about having the immune system of a “Victorian child.” The remark was taken seriously by management, resulting in demands for medical approval for a condition that does not exist. Even after clarifying it was a joke and requesting documentation, the employee was terminated the next day.
