De Vet Du, or at times De vet du started in Lidingö, a suburb of Stockholm by four friends Christopher Martland, Johan Gunterberg, Tor Wallin, and the so-called "DJ Hunk".

[5] Moving to music and humor they posted their first video "Dansa Är Kul (Men Jag Föredrar Å Supa)" (meaning "Dancing is fun, but I prefer to drink" in Swedish).

Their regular online postings, filled with tongue in cheek humor, puns and self-deprecating hilarious criticism of social phenomena, attracted a big following.

These include releases such as "BoyBand", the album Shit Va Pin, "Hon va en han", "Sture P", "Bågar Utan Glas" and "Din Syrra".

[7] De Vet Du is featured in Björn Borg commercials, particularly the memorable "Boxers or Briefs" series.
