The Warners and the Hughes invite the neighbors, Rob and Wendy, and their kids over. Greg decides to join a gym after seeing Rob give rocket ship rides to Sam, because he's too exhausted to give them to Sam himself. But Greg has no idea what to do at the gym and contemplates hiring a personal trainer, which Jimmy thinks is a waste of money. So he volunteers to personally train Greg himself. Christine, meanwhile, thinks about taking Logan out of day care because she's bored. Kim instead convinces Christine to go down to a temp agency and get a part-time job that she's qualified for -- passing out teeny-weeny samples at the supermarket. Jimmy loves Christine's new job -- especially the free lunch part -- but Christine hates it so much she quits, and tries her luck again at the temp. This time she gets an even worse job, and quits it too. Jimmy overworks Greg so much that he's ready to quit working out himself, until Jimmy confesses that he's only been ""helping"" Greg to avoid taking care
