Lisa decides to bring the family to the museum to see a weaving exhibit for her summer vacation, but they soon discover that it has been replaced by a "History of Weapons" exhibit. Faced with an incredibly long line, Homer notices Ned Flanders and his sons at the front of the line and cuts in front of them. Everyone else starts taking advantage of Ned’s kindness as well until the Flanders family is stuck at the end. At the end of the day, they are still waiting, and are denied entry, as it is closing time for the weapons exhibit. They decide to check out the human evolution exhibit next door. Ned is outraged to hear that humans actually evolved from apes and that the creation account in the Genesis is therefore a myth. Covering his sons' eyes, he forcefully drags them out of the exhibit.
