Last time we heard from the 'What does the fox say?' Ylvis boys, they were singing the praises of the US state of Massachusetts and generally being a bit weird, but this time they're back with a prank that we really can't believe someone hasn't thought of before.

People often complain that IKEA is a maze and black hole that somehow manages to consume your entire day when you visit, so Ylvis decided to take that one step further and trapped people inside room sets inside it. Mean, yes. But very, very funny.
