What's the strangest thing you've carried across a border?

Bringing a can of surströmming on a plane
not being charged for terrorism

You would have made headlines.

Bring me some Surströmming if you ever come to Australia.

What's the strangest thing you've carried across a border?

me

empty can of coke

Zika Virus and Chikungunya huehuehue.

Kidding, never more than 300 miles.

As I was 13 years old I brought one pallet Red Bull (24 cans) from a gas station in Austria to Germany (we was on the way home from vacation).
Back then it was forbidden to bring Red Bull into Germany. Luckily we passed the german border without customs inspection.
As we arrived at home, I told my parents that Red Bull is strictly banned in Germany. ( ͡° ͜ʖ ͡°)

But times change and later it was possible to buy it everywhere. Legal! :D

Let me think... the only foreign countries I visited were Vatican City and San Marino, but given that they're enclaves, I don't think that would count as crossing Italy's borders...
So, the strangest thing I carried was... a nail clipper, most probably...

Oh, I feel you mate! I was confiscated a can of mackerel in spicy tomato sauce at the Heathrow airport :(

When I was 14 or 15 I took a street name sign over the the Welsh/English border after a family holiday. Now that was illegal as I stole it, but it's not in the realms of drug smuggling or gun running etc. The Welsh/English border isn't really a proper border either, but it's the best answer I can come up with.

It was on the ground, and I think a car must have hit it and knocked it out of it's stand. Pic of the type of thing below for reference, but it's not the one I took. The name of the street had a nice ring to it in my opinion. I thought the sign would look good on my wall and act as a souvenir of the trip.

You are the reason we can't have nice things! >:( Shame!

When I've been visiting my family in Slovakia as a kid, we got a ton of chocolate. Regular bars, Milky Way, you name it... The trip was ~150km. In the midst of summer. So we have carried maybe a kilo of liquified chocolate. Still yummy, though.

My aunt and her daughter are in the antiques business. My aunt lives in Normandy where she is restoring a chateau and I had been over there helping out, but I was on my way back for a while and she asked me to carry a bag of antiques with me on the ferry to hand over to my cousin who was trading in the South in the England. I did this, and this and only after the fact discovered that the bag contained various nazi artifacts that had been dug up at Grandcamp-Maisy including a grenade (not live), a bayonet and various swastikas.

A boat made out of seashells when visiting Mumbai. And a 5-gum pack from Florida.
Oh yeah, and a fridge magnet with the shape of a drunk cow when in Andalucía, Spain.

...Holy fuck, I'm a pretty damn boring traveler.

A Kinder Surprise Egg in USA by plane. Was charged with terrorism, now I serve my time in Guantanamo prison :D

probably a small keg of Jupiler, a Belgian beer (they have the best beers in the world). it was a gift from friends when I visited and it took up about a third of a suitcase. when it went through the x-ray they had to open the case and then the customs official complimented the choice and told me I should've thrown away the rest of my stuff and just gotten more beer
not the most exciting of stories perhaps, but best I've got since the "myself" answer has already been used :P

a Chack.

A teddy bear. In my backpack. With my laptop and other personal belongings. Every single time I travel. I only occasionally get a raised eyebrow for that. Did I mention I'm 23?

Hmm.. When 80% of my suitcase (quite a big suitcase) was filled with CD's I had bought at Tower Records in Tokyo, perhaps. Otherwise I can't think of anything right now

Mullins.
In reality nothing. I am not interesting person, so at least have a bump ;_;

I went to London with my mom, we flew into Heathrow and our bags were scanned, checked, and sniffed, and we were padded down. My mom had to hand over her lipstick and they checked it for illegal substances...
When we got to the hotel I took off my coat and 3 darts fell out of my inside pocket...

A handmade marionette constructed from misc materials that took a very, very long time going through the x-ray scanner.

Whole computer without case (vga, psu, motherboard, ram,hdd) in a hand luggage, and another time a lot of bacon, sausage, half kg paprika (spice), 1 kg tobbaco. From hungary to uk, with ryanair.

I don't have any good stories to add (I'm pretty boring), but I have to say, I kind of want to try Surströmming.

I had to google the best way to eat it an found, "The most common way to consume surströmming is with tunnbröd (thin bread) which is a soft or crisp very thin bread commonly baked in the north of Sweden. The bread is consumed in Sweden all year. Usually a sandwich is made with surströmming, butter, potatoes, sour cream and diced onion."

That...sounds delicious. I tried to find something describing the taste but came up empty (plenty of videos of people trying and going, "ewwww" though...sigh).

Myself....

A four pint unmarked plastic container of beer - well strictly speaking my wife did it rather than me. It was whilst we lived in Sri Lanka and although there were some decent bottled beers out there it was a rare treat to have some "proper" beer to drink. Apparently the customs guy was somewhat bemused when she took it through but didn't stop her :) That was in more naive times

I accidentally carried a knife and fork I'd used when visiting tribes in Africa in my hand luggage.

I had to apologise profusely and say I wasn't trying to hijack the plane with my blunt butter knife.
