Kurtwood Smith makes a guest appearance as cousin Jacob, but he has no interaction with Joseph Gordon-Levitt (Tommy), French Stewart (Harry) or Wayne Knight (Officer Don). Joseph Gordon-Levitt, French Stewart and Wayne Knight have all appeared in different episodes of "That '70s Show," which starred Kurtwood Smith, but none shared any scenes nor had any interaction with him. Kurtwood Smith (Jacob) and Courtney Peldon (Janine) shared a scene but had no interaction in both this episode and an episode of "That '70s Show" ("Hyde Gets The Girl", s4e4). Julie Claire (Jenny), Kurtwood Smith (Jacob) and Joseph Gordon-Levitt (Tommy) all appeared in "That '70s Show" (s1e11, "Eric's Buddy"), but Julie Claire interacted only with Kurtwood Smith. "3rd Rock From The Sun" and "That '70s Show" are both Carsey-Werner productions, created by Bonnie and Terry Turner.
