Morgenbesser is leaving a subway station in New York City and lights up his pipe. A policeman tells him that there is no smoking allowed. Morgenbesser points out that the rules cover smoking in the station, not outside. The officer concedes the point but says "If I let you do it, I'd have to let everyone do it." Morgenbesser retorts, "Who do you think you are, Kant?" and finds himself hauled off to the police station.
