The judge brings his young daughter to the Stones' home to be examined by Dr. Stone. The doctor takes the girl's temperature, and announces that she has a fever resulting from "a 24-hour virus that's going around". He takes the thermometer from the ill girl's mouth, places it back into its carrying case, and inserts the case into his jacket pocket, without ever having even wiped (much less sterilized) the now virus-infected thermometer.
