Barrett and John return with new problems and new solutions! This week Barrett has been binging Highway to Heaven, whilst John has been frugal with just about everything, including his electricity! A letter from Mary starts off the solving; she and her dad are big metal tinkerers, but her dad sometimes hurts her when at work. The boys have differing strategies, but eventually they find common ground. Then, John has his most irritating Roleplay guest yet, in the form of monotone, monosyllabic Philip. Trying his hardest, John assists Philip with his upcoming dinner date, but will everything be ready on time?
