Ned meets up with the church council to suggest promotion of creationism. The next day, he and Reverend Lovejoy blackmail Principal Skinner into introducing creationism in the school. Lisa is perturbed by this, and at a town meeting asks everyone to make a choice between creationism and Darwinism, as there is only one truth. The townspeople vote for creationism, much to her chagrin, and the act of teaching or learning Darwinism and evolution is made illegal. Lisa therefore decides to start holding secret classes for people interested in evolution. However, just as the first lesson is about to begin, she is arrested by Chief Wiggum. She asks why she is being arrested when there are far worse crimes out there, and embarrassed he tells her they only have enough manpower to enforce the last three laws passed, even stating that this is the worst law system there is. Lisa is brought to trial, which is dubbed "Lisa Simpson v. God". Representing her is Clarice Drummond, an ACLU lawyer, while on Ned's side is Wallace Brady, an overweight, southern lawyer. The trial does not go smoothly for Lisa, as Professor Frink gives ambiguous answers regarding God's existence, while a creationist says that evolution cannot be real, as there is no proof of a "missing link" (depicted in a picture as a savage hominid, holding a rock over his head).
