Bob is a Conspiracy Theorist who believes he has found undeniable proof that he's right. He sets up a huge reveal... and while it turns out there is a conspiracy, he's completely off about one vital aspect that ends up turning him into a laughingstock or otherwise breaking him.
For instance, Bob is from the Deep South and finds it strange that there's so little historical information about one of his ancestors, and what little information there is paints the ancestor in a very bad light (such as being a slaveowner who beat his slaves to death). He finally finds diaries about townsfolk privately confessing they lied in court and hid the truth about the man, reveal where all the evidence is hidden, and Bob, convinced he's going to right a historical wrong and prove his ancestor was an abolitionistn ges to dig it up... and the evidence shows that the ancestor was even more of a Complete Monster than Bob thought (not just a slaveowner but a pedophile and obviously got off on beating said slaves to death), and the conspiracy was actually townspeople hiding the evidence that such a loathsome criminal could even exist to avoid bringing shame on their town.
