What is the theme in Tevye the Dairyman and the Railroad Stories by Sholem Aleichem?

Both Tevye the Dairyman and the Railroad Stories involve much humor against authority and the bureaucracy. This is clearest in the short story, the Automatic Exemption. In this story, a boy named Itsik is drafted, although he has an automatic exemption as an only child. On the one hand, Russian Jews generally resent the Russian state and try to avoid being drafted into the army. On the other hand, the Russian bureaucracy tends to become confused and is totally inefficient. The authorities confuse Itsik with his dead brother Eisik, and with Itsik's nickname of Alter. This story is also the perfect example of an extreme joke around a case of mistaken identity.
