Ed and Rachelle get a special visit from recently retired IT engineer Bruce Fong and his 88 year-old mother, Lois. They travel back in time to discuss the perils of Chinese immigrants, and what it was like to attend USC when tuition was only $375 per quarter. Bruce also starts a competition with his 8 kilowatts of solar, Ed prepares some beets from the garden, and Lois reveals how she's kept her mind and body in such tiptop shape without even dieting.
