By now you will almost have certainly heard or read about the viral Facebook group which is calling on people to storm Area 51 - the famous US military base that supposedly is where they keep the aliens.
But whereas most people have poopoo'd the idea of people trying to force their way into one of the most heavily guarded places on the planet, YouTube sensation PewDiePie - real name Felix Kjellberg - says he thinks it makes 'a lot of sense'.
In his latest meme review vid, the 29-year-old took the opportunity to address the internet storm surrounding the bizarre event.
He said: "That actually makes a lot of sense. Like, what are they going to do? If a million people show up, what are they gonna do, okay?
"Finally, we'll get to see all the cool stuff."
Of course, he's joking and spends the rest of his video looking at a series of memes that have been created around the plans to storm Area 51. All of them hilarious.
At the time of the Swede's video, the Area 51 event page - 'Storm Area 51, They Can't Stop All of Us' - had 841,000 people listed as attending.
However, since then the numbers have grown and grown, with now more than 1.3 million signed up ready to fight the cause. Or not.
The Facebook event was set up a few days ago and asks people to tip out outside the top-secret base in Amargosa Valley, Nevada in the early hours of 20 September 2019 to get into the base.
The event description reads: "We will all meet up at the Area 51 Alien Center tourist attraction and coordinate our entry. If we naruto run, we can move faster than their bullets. Let's see them aliens."
If you are one of those signed up, before joining this band of pioneers on their journey to almost certain death, you should probably listen to the advice of some people who might know a thing or two about this. For example, US Air Force spokesperson Laura McAndrews.
McAndrews told The Independent: "[Area 51] is an open training range for the US Air Force, and we would discourage anyone from trying to come into the area where we train American armed forces.
"The US Air Force always stands ready to protect America and its assets."
But that's what I would say if I was hiding secret alien technology.
