"Say Ja to the amazing Swedish diet" these girls sing. Much like the Swedish Bikini Team, these gals dress only in blue and yellow, have lots of blond wig-hair, and pose in front of Swedish stuff like
fjords, windmills, snow covered mountains, and on vespas or while asphalt-skiing. That last thing is actually a common Swedish phenomenon. It's your regular diet drink sold by CVS, and the ad is a parody of a parody of a parody. There's something very Swedish about that.
