Mjällby AIF reportedly made an April Fools' joke on its website three years ago, announcing that Head & Shoulders would become the new main sponsor and the club would change its name to By AIF. According to reports, 50 percent of that joke has now become reality. The joke involved a video call between Mjällby's Daniel Hjalmarsson and anti-dandruff ambassador Henrik Lundqvist.
Sources indicate the prank likely elicited laughter and surprise among some fans.
