Screenwriters Harry Ruby and Bert Kalmar were standing on the set one day when an extra standing next to them said, "I don't know who wrote this stuff but they ought to be arrested...they should be in a different business." Kalmar, who was known as a rational and calm man, said to Ruby, "I'm going over to hit him. Who does he think he is? He's just an extra!" Eventually, Kalmar and Ruby were informed that Chico Marx had paid the extra to say that and arouse the screenwriters’ anger as a joke.
