For example, in the beginning, he sets up the joke by stating that he feels perfectly safe in New York City. He elaborates on his statement by stating three reasons (1:14-1:24). The first item he lists are the “murders” that we unconsciously associate with criminals. This assumption is strengthened when he states the next entry as “child molesters.” Immediately, a pattern of criminals is created in our brain. However, when we discover that the next word is “Jews,” the pattern breaks, creating surprise and shock, and for some perhaps even offense, thus resulting in the punchline of the joke. Likewise, when Louis CK sees the bat and describes his reaction, he also uses the rule of three. First he “crawls into a closet,” then he “locks the door,” and finally he “calls emergency services” (3.22-3.28). Once again the pattern is broken because you wouldn't expect a person to call 911 just because of a bat in their hand
