During her research, Lisa shows Homer her work. Grampa is behaving in a rude and irritated manner and therefore Homer concludes that if the flower has the effect of making hostile scorpions docile, then the flower must make angry Grampa's docile. He sprays some of the Silvertongue's water in Grampa's coffee and the following morning he has becoming increasingly optimistic, more so than usual. The effects of the Silvertongue water are so astonishing and unique that a German doctor soon finds out about this unique effect and, after testing the water on Grampa, extracts the right solution and duplicates it using beautiful German women as experiments. The doctor warns the Simpsons that if the solution fell into the wrong hands it would get into the black market and thus cause major damage to his reputation. Inevitably [[Bart]] seizes the opportunity to make money and sells the drug to miserly old citizens of Springfield, including [[Agnes Skinner]], [[Charles Montgomery Burns|Mr Burns]], and numerous residents of the Retirement Castle.
The solution appears to have indeed increased the optimism of the elderly, until Grampa's eyes pop right out of hisface when he is telling Lisa how good he feels about his life. Lisa and the Simpsons are shocked at how such a good drug could have such a bad effect, and Lisa sees the scorpions from Satan's Anvil have their eyes popped out of their head as well. Marge is initially relieved that only Grampa has had the Silvertongue solution, until Bart admits he has sold the drug to numerous residents of the town, causing an outbreak of blind people, most of them elderly.
The old blind people converge together to form what initially seems to be an angry mob, but then Grampa explains to them that the biggest mistake they made was letting Homer's generation get away with doing nothing with all the products of his generation's hard work. Grampa and the elderly blind citizens push their eyeballs back in, restoring their vision, and set about giving Homer and his generation something to live for, as opposed to the mob-like attitude they had earlier. Or as Homer puts it, the last generation's "can do" attitude balances out his generation's "won't try" attitude.[[File:Aba.png|thumb|Cranky Abe]]
