S3E8 Latka's Cookies

After Latka's grandmother passes away, he is thrilled to inherit her beloved cookie recipe along with the secret ingredients. He bakes a batch for his fellow cab drivers, but they aren't impressed. Undeterred, Latka launches his own cookie venture. Surprisingly, the cabbies soon find themselves craving the cookies and feeling inexplicably joyful. When Jim tries one, he discovers the secret ingredient is cocaine, explaining the odd behavior. Concerned, Alex drops by to break the news to Latka, who is high from the cookies and imagines Famous Amos urging him to chase his dreams. Although he can't sell the drug-laced cookies anymore, Latka embraces the thrill of entrepreneurship, believing he's finally living the American dream.
