A man took his wife to get tested for COVID-19
Two days later, he got a call from the lab.
Doctor: I'm sorry to inform you that your wife's test result were mixed up with another patient's test result. We're not sure if she has COVID-19 or Alzheimer's disease.
Man: So what am I supposed to do now?
Doctor: Take her out for a long walk and leave her. If she manages to find her way home, don't open the door.
