Maggie's parents Ed (Gordon Jump) and Kate (Betty McGuire) conspire with the Seaver kids to arrange a surprise 20th anniversary part for Jason (Alan Thicke) and Maggie (Joanne Kerns). Alas, the festivities quickly degenerate into a shoutfest involving Maggie's mom and dad, Jason's mom Irma Jane Powell), and the rest of the guests--culminating in one of TV's sloppiest food fights. Even so, the party proves to be a boost for the blossoming relationship between Mike (Kirk Cameron) and Julie (Julie McCullough). ~ Hal Erickson, Rovi
