Who? Harry Anderson, Markie Post and Charles Robinson as themselves on "30 Rock's" episode "The One With the Cast of 'Night Court'" Why? Kenneth wants a satisfying ending to "Night Court" and Tracy wants to give it to him. They rally three of the old cast members and write up a big wedding scene between Anderson and Post. Too bad the stars get caught up in old pettiness like who's still friends with John Larroquette and who got snubbed at the Emmys.
