Tom and Natalie call Greg to say they're coming for a visit, because Natalie won Tom a walk-on role on JAG in a charity auction. Greg wants his parents to stay in the guest house, so he nudges Kim to ask Jimmy and Christine to sleep on the living room couch and send Logan to Dominic's room. Kim, who doesn't want the critical Natalie around, is relieved when Jimmy tells her that she'll likely be spending the whole day on the set, since JAG does day-long shoots. Kim's elation is crushed when Natalie says that she isn't going with Tom, she's staying home. Tom anxiously awaits his film debut as a jury member, as it's the first time he's ever acted in front of something besides his mirror. One of the other extras fills him in on how he and all the other ""background actors"" (as they prefer to be called) have perfected personalized moves to help them get discovered. Greg, Natalie, Jimmy and Christine see for themselves just what moves Tom invents when Greg brings home a tape of the dailies. W
