It turns out that the easiest IKEA product to assemble is an illegal sleepover.
The kids' video got over 1.7 million views, and is inspiring copycats around the globe. The BBC reports that two 14-year-old girls were caught after spending the night at the branch in Jonkoping, Sweden.
It's somehow cooler and less twee than the 500 Days of Summer version.
Ikea does have some chill, and decided not to formally charge the 14-year-olds because of their young age.
But now they're telling youths to stop it. A UK spokesperson told the BBC:
"We appreciate that people are interested in Ikea and want to create fun experiences, however the safety and security of our co-workers and customers is our highest priority and that's why we do not allow sleepovers in our stores."
Way to be a party pooper, IKEA.
