Route 66 (S02E06)

Karl dreams of cruising the iconic Route 66 in a convertible Cadillac, but Ricky and Steve have different plans. They convince him to take detours that include joining a high school choir, spending time with New Age therapists, and interacting with the Amish community. To top off his adventure, they plan for him to experience the thrill of wingwalking as the grand finale of his trip.
