Jonathan and Joel Salomonsson, 15 and 16 years old, got the shock of a lifetime when the huge northern pike ('gädda' in Swedish) latched on to their hook on a fishing trip over the weekend.
One of the most common types of fish in Sweden, the pike is one of those catches anglers like to brag about after a day on the lake, with sizes ranging from 70 centimetres (28 inches) long to however much the fishing buffs feel brave enough to lay claim to on any given day.
Sweden's biggest ever pike was reportedly pulled up in the Järnafjärden lake in 1986, weighing in at 26.57kg (59 pounds). However, most stories are based on rumours and are difficult to verify.
But luckily for the two northern Swedish teenagers, they had their smartphone at hand and managed to get video proof.
Joel filmed as Jonathan struggled for several minutes to haul in the beast, which turned out to weigh 14.09kg and measure a whopping 123 centimetres (as much as the height of an average Swedish seven-year-old).
“Holy shit, holy shit,” one of the young anglers shouts in the video (speaking in English like a good bilingual Swede) which quickly went viral in Sweden on Tuesday, with many amused at the cousins' exalted reaction to their catch.
"This could be the funniest video I've ever seen," commented one viewer on YouTube.
“First it felt like a normal pike at around 3kg maybe, but then it got closer to the boat and we screamed and got so much adrenaline. We could tell that it was a monster, that it easily weighed more than ten kilo,” Jonathan told regional Swedish newspaper Norran.
“It cannot be described,” he added. “It was scary.”
The boys have so far refused to reveal where exactly they caught the fish, hinting that it was in a lake near Arvidsjaur in the far north of Sweden.
