While sitting in the coffee shop, Jerry and George resolve to grow up and take life more seriously. Jerry decides to call the woman he recently broke up with - because she shushed him. For his part, George has been thinking a lot about his former girlfriend Susan. After imagining the ideal life they could have together, he goes to her apartment and proposes. She accepts and George almost immediately begins to have second thoughts, especially after Jerry breaks up with his girlfriend a second time. Elaine meanwhile is having trouble with a neighbor's barking dog and enlists the help of two professionals to get rid of the problem: Kramer and Newman.

Jerry, George, Kramer and Elaine get stuck in standstill traffic due to the massive Puerto Rican Day Parade.
