Even though it's supposed to be the "show about nothing," Seinfeld actually provides something of a continuity from one episode to the next throughout its fourth season. Things get started with the two-part "The Trip," in which Jerry and George head to California for the purpose of locating Kramer -- who has delusions of stardom since his Murphy Brown gig, and appearing on The Tonight Show. This little escapade segues into a plot strand wherein NBC executive Russell Dalrymple asks Jerry to develop a sitcom about his life. By the time Elaine returns to New York after a trip to California, the sitcom deal is gone, but not forgotten, as it continues coming back to life for the duration of the season, culminating in the hour-long season finale, "The Pilot." In other classic moments, Jerry and George visit "The Bubble Boy"; the gang makes its first foray to a theater showing "Rochelle, Rochelle"; and the famous "yada yada yada!" episode.
