Homer and Bart build a model rocket together but lose control of it as it burns down the church. Without any money for repairs, the church decides to sell out to corporate sponsors: mainly Mr. Burns. Lisa is appalled by the shameless display of billboards and corporate monikers emblazoned on the church walls and finally decides to simply quit the church for good. She decides to test out new religions and finally happens upon a Buddhist temple.
Lisa becomes enamored with the easy-going approach to enlightenment and decides to take Buddhism as her new religion. Her family, worried abut her soul, try to bring her back to Christianity by subtly dropping Christian innuendo. Lisa realizes that Buddhism allows for the celebration of all holidays and finally comes back to her family to celebrate and simply pay "lip-service" to the church.
