The viral success of the 'Storm Area 51' Facebook joke is inspiring copycat events, with calls now to raid Loch Ness, the Bermuda Triangle and North Korea.
The original, 'Storm Area 51, They Can't Stop All of Us', has nearly 3.5 million people interested or going. The plan - a joke, according to its creator - is to gather in September to raid a secretive military base in Nevada where it's suggested the US Air Force has alien bodies and technology.
The US military has warned against it, noting that it is authorised to use deadly force against anyone who tries. So instead, pranksters are suggesting raiding other places they might have heard about on The X-Files.

'Storm Loch Ness, Nessie can't hide from us all' suggests invading the icy Scottish lake that for nearly a century has been claimed as being home to an aquatic monster some have suggested is a leftover from the dinosaur age.
More than 70,000 people have signed up, but like at Area 51, the authorities are warning against it.
"With no US Army involved, Loch Ness looks a little less hazardous than storming Area 51, but here we have our own set of problems," the Loch Ness Royal National Lifeboat Institution (RNLI) said on Facebook.
Firstly its lifeboat can only carry a few people at a time, not tens of thousands. Also, Loch Ness is 230m deep and very cold - averaging 6C year-round - and has unpredictable conditions.
"Weather conditions and water state can deteriorate rapidly, going from flat calm to a large swell in minutes," the Loch Ness RNLI said.
For those who are too afraid of Nessie, there's 'Storm the Bermuda Triangle, It Can't Swallow All Of Us'. About 45,000 brave souls have signed up to enter the notorious patch of ocean in the western Atlantic.
Contrary to popular belief, there is little evidence the triangle - between Miami, Puerto Rico and Bermuda - actually has a higher rate of disappearing planes and boats, considering the amount of traffic that passes through it.
The organisers say there will be a real event in Miami scheduled for October 1, raising money for cancer research and wildlife efforts.

Organiser Anthony Dominick Carnovale told Fox News he's hoping people will attend his Spongebob-themed party instead of trying to storm Area 51.
"I honestly just don't want people to attend the Area 51 event because I don't want people getting shot or arrested."
Closer to home, Kiwi joke 'storm' events include 'Storm Mangere KFC, they can't stop all of us' and 'Storm Newshub to respectfully ask Paddy Gower to storm Area 51', which has 8700 people interested.
"Don't touch Mr Gower or the almighty John Campbell will curse your soul," the page reads, referring to the former 3 News and Campbell Live journalist, who left MediaWorks in 2015.
