Americans just discovered this niche Aussie Christmas tradition. They're stunned.

Hold the phone. The Americans have questions.

Apparently, there's a very specific Aussie Christmas tradition that… we didn't even know was a tradition until some questions arose from a Bluey episode.

A post has gone viral in the 'Australia' sub-reddit group.

It was a screenshot of an episode still where the Heeler family are enjoying Christmas lunch together.

The image was posted on the 'Adult Bluey Fans' Facebook group where the poster asked: "What are the hats they wear in 'Christmas Swim' and what do they signify?"

In the image, the characters are all wearing paper crowns they, of course, got from the Christmas crackers they all opened up. Are you following along? Well, the Americans are not.

Apparently, the flimsy paper crowns we get from pulling apart bon bons with our families are a uniquely Australian thing.

I had no idea these oversized thin pieces of paper we wear for "silly" photos would cause such controversy. And I also didn't know this wasn't a worldwide Christmas tradition.

The Reddit poster who made everyone aware of this question in the Bluey group said "Apparently the rest of the world doesn't do paper crowns at Christmas."

However some commenters pointed out that it's not specifically just an Australian thing but a British Commonwealth thing. British movies and TV shows with Christmas celebrations also show characters waring the trusty paper crowns, like in Harry Potter and the Order of Phoenix.

I then saw a comment that made me fear for my life (sorry to be dramatic). It said: "Next minute, Bluey episode solely responsible for worldwide bon bon shortage due to unprecedented must-have FOMO demand from US market."

Now… surely this was said as a joke (right guys?… Guys?). But there's something in me that just truly believes my family won't be able to afford Christmas crackers this year.

What are we going to do without our crappy little hats and our useless mini bag of marbles or tiny plastic car? Lest we forget the God-awful Christmas-related joke that we're all forced to read aloud at the table. If I have to hear "What type of photos do elves take? Elf-ies!" one more time, I swear I will breakdown in front of my entire family.

If you're American and reading this… trust me, this is not a tradition that you want to adopt. Leave it to the experts. It takes time and endurance to build up the mental load of little Timmy not "winning" the prize end of the Christmas cracker five times in a row.
