Norwegian teenagers are recovering from the country's annual three week booze and prank festival where revellers compete in lewd dares ahead of their exams.
While the A Level students of Britain have been diligently revising, recapping and readying themselves for the start of exam season this week, in Norway the preparation is quite different.
From the middle of April to May 17 18-year-olds in the Nordic nation dress up in colourful outfits to ride around in themed buses that cost tens of thousands of pounds and generally drink themselves into oblivion.
They do so as part of the russefeiring or russ tradition, which dates back to 1905 when students were given different coloured caps based on the subjects they were soon to be graduating in.
Over the past century it has turned into the mother of all benders in which local firefighters come out to blast teenagers with their firehoses and the russ (as the participants are known) dunk younger students in water.
As part of the celebrations the naughty Nords carry out dares to earn themselves a piece of protein bar paper which they then tie into their specially coloured hats.
According to one participant, tasks include pole dancing on a street lamp for five minutes in a crowded place, reading "loudly and with passion from a porn magazine when a teacher asks you about something in class" and having "sex in the woods".
You might also be urged to sit through a whole class in your underwear, stuff a Big Mac down in two bites, "eat a whole bag of Cheese doodles, then go make out with someone who doesn't know about it" or simply break up with your partner.
Others have spoken of being dared to spend the night outside, ask strangers for condoms and crawl through a shopping centre on all fours "like a dog".
Two students were made to wear loaves of bread instead of shoes for a day.
A big part of the celebrations involves hiring a big bus with a huge sound system to drive around the country in, showing off the elaborate decorations and paintwork revellers cover them in.
Even with Norway being one of the richest countries in the world per capita with minimum wage a cool £17 an hour, the most impressive buses and their £100,000 price tags still require students to pool their resources and ask their parents for financial help.
Whether in such a vehicle or a smaller, more modest van, russ head to the woods to have huge blow-out parties.
Patricia Svendsen, a former student in Norway, previously told news.com.au: "The school year starts in August and you immediately start planning Russ. There are pre-Russ parties all the way until May.
"It’s pretty epic. Some kids save money, or get tons of money from their parents, and then they go ahead and buy themselves a bus — a whole bus.
“And then they style the inside of it as awesome as possible, buy the biggest speakers they can and get someone to spray paint the outside."
Even with the sweeter part of the tradition which sees younger children ask russ for special fake business cards with their slogan and a funny picture on to build their collection, not everyone is happy about the celebrations.
Many gripe about the chaos caused by the partying teenagers, the mess left on the streets and the pounding music which drifts through town centres at night for much of the three weeks.
"Why has it become normalised that russ celebrations have become synonymous with bothering people?" one unhappy person wrote this year.
"Every g*****n night for weeks up to May 17 this madness continues. It's supposed to be a curfew between 11pm and 6am. So why can't the police stop this?
"The russ drive around and around the residential areas here every single night, solely to bother people. It is not reasonable to simply believe that people should stop sleeping for one month straight. The police don't give a s***."
Another added: "Boring advice: Call the police every time. This is disorderly conduct, which is punishable. This gives you reason to call them every time it happens. Then they may not do anything about it, but that's their business, you report. Then you get your neighbours to do the same.
"Give it a week of 5 calls every night and the log will start to show that there is a problem. One grumpy guy, one night, is not a problem. That's 20-30 grumpy posts in the log in a week."
