That would be even more shocking.
If our government decided it didn’t need an army bigger than the next dozen largest countries combined, cut back on everything and split the money: half to paying off our horrific debt and half to making the world a better place.
Melania coming out of hiding and convincingly showing that she is in good health and spirits and loves and respects her husband.
(Actually, the idea sickens me more than it would shock me since I wouldn’t put it past you know who to force it.)
Why would I want to show off in public and end up in a lab?
Trump’s message backfires horribly, and the next president of the US makes Bernie Sanders look like a timid right-wing Democrat; Venezuela cuts all ties because new POTUS is too radical; the whole thing succeeds and everyone is happy. THAT would shock me. 
I lol’d 
If people finally came out and said “You know what, the opening of the pilot episode of The Newsroom really wasn’t that good. Why would a college student ask why America is the greatest country in the world unless her entire plan was to allow the main character to give a speech showing how amazingly cognizant and smart he is”
I’d trump that with the inverse…the WWE admitting that it’s all real, they’re not playing characters, they’re actually fighting.
One word—Dino-chickens.
Incontrovertible evidence that ghosts exist.
And CNN devoting 15 minutes to a news story that doesn’t involve Trump or a school shooting.
Not shocking at all. He’s not particularly an ideologue and has supported abortion rights and gay rights in the past. He has waffled on gun control. Basically, he goes whichever way the wind blows. He’s a populist. If the polls showed that his base wanted free abortions for all, tomorrow he’d be on Twitter telling us that he personally is going to kick pregnant women in the stomach and that has been his position all along.
That wouldn’t bother me at all. Now what I would find shocking is him announcing he has been married for the past 18 years and has no intention of giving up his wife or his position. You can select a wife of either gender if you wish.
About the only thing that would totally shock and amaze me to the point of speechlessness would be either or both major political parties announcing they are disbanding so that we can get back to being a country closer to what was originally formed and framed – of the people, by the people, and for the people – rather than for and by a group of professional political hacks.
“And in a shocking announcement, Bigfoot has been found! This is no joke! A farmer in Montana has captured Bigfoot. Scientists have confirmed this is indeed Bigfoot.”
“This just in…THE BIGFOOT IS A FEMALE AND IS PREGNANT!!!”
I just found out yesterday that Shaun T (the coach from Insanity) is gay, and I was flabbergasted. As much people say that gay men are no different from anyone else, I haven’t totally internalized that yet, and I still have this mental image of a gay man being effeminate. And Shaun T is so manly! I know this thread asks “what *would *shock you,” not “what did shock you,” but since I only found out yesterday I think it’s close enough to count.
On his deathbed, George HW Bush confesses - he shot JFK.
I thought the OP was talking about something remotely plausible.
Mine would be -
“Former President Barack Obama was arrested last night on charges of domestic abuse in connection with an apparently cocaine-fueled incident between him, the former First Lady, and a person described as a ‘personal friend of the President’…”

That would do it for me. It just feels more plausible than a supernatural event or a politician suddenly reversing himself. There’s just enough suspicion.
Then again, the Tim Donaghy surprised me that it wasn’t a bigger story: “rogue ref, end of story”.
How about a popular player admitting he threw a game. Like Russell Wilson throwing that Super Bowl INT on purpose. Or Pete Rose admitting he bet AGAINST the Red.
This reminds me of the over-gasping scene in Futurama 
That dogs can really understand English and could talk. They just don’t want to talk to us. “There is no intelligent people here”
