Then there was the great Newlywed Game cover up. For years there was a rumor of Bob asking a question on the Newlywed Game: 'Where was the oddest place you ever had sex'...or something to that effect was the claim.
It was claimed the wife said something to the effect of 'Up the butt Bob'.
Snopes went to great lengths to discredit it, even contacting Bob about it. He denied it ever happened. Snopes declared it false, there was massive debate and questioning their methods and conclusion. Snopes held their ground.
Then one day they re-ran the episode. She said 'In the ass, Bob'. Took Snopes some time to correct the story, and they rewrote it to make themselves look less stupid.
