Walter's War

S4, E19: Walter falls in love with Julia Myers, a WW II buff, and invites her over to the Powell home for dinner to impress her with his war memorabilia. Unfortunately, he forgot that he ordered Charles to throw them out when he cleaned the house. To remedy the situation, Walter decides to borrow some replicas from his veteran group, the John Paul Jones Society -- he has an authentic-looking bomb, a Japanese sword and flag delivered to the house. At dinner that night, Charles joins Walter in impressing Julia with the war memorabilia. But after a while, Walter starts to feel guilty about lying and confesses the truth to Julia.
