Viasat Sport: The Great Bajen Prank, 1

In an advert in the Swedish football magazine Offside, Viasat Sport celebrates all the Champions League winners, as well as the champions of its predecessor, the European Cup. But instead of Aston Villa in 1982, it's ... Bajen (!).
Bajen (or Hammarby IF as the football club is also called) has never been near a major European title. The whole thing is a prank from the advertising agency M&C Saatchi, co-founded by the Bajen enthusiast Patrick Dry.
Footnote: 1982 was certainly a good year for Bajen that includes the national final, but lost against IFK Goteborg. Hammarby got kicked out in the second round against Finnish FC Haka in the UEFA Cup. It should be said that Hammarby actually have a "Euro-title" but only in low-ranked Intertoto Cup, 2007.
