The Duggars are hardcore conservative evangelicals, which means they adhere to beliefs that the rest of society abandoned long ago.
In order to ensure that the cycle of ignorance continues through the generations, they need to teach their kids some profoundly idiotic things.
Back when the show was still called 18 Kids and Counting, the Duggars took their children to the Creationist Musuem Ark in Petersburg, Kentucky.
It was one of the family's most defiantly stupid episodes, and it resulted in a whole lot of cringe.
And sadly, it's one we won't soon forget.
