Mike shares a trivia fact about Reformation Day (October 31), explaining that Martin Luther nailed his 95 Theses to a church door as a culturally normal form of public announcement, not as an act of defacement.

Mike notes it is the 501st anniversary of the Reformation and corrects a common misunderstanding: nailing documents to a church door was the equivalent of posting on a public bulletin board since churches were the primary gathering point. Luther originally intended to reform the church from within, not split from it. The split came later.
