Hatten är din
Hatten är din (Swedish for "The Hat is Yours") was a popular internet meme from 2000. It's a flash animation featuring the music of Azar Habib and what appears to be a party with various people wearing traditional Turkish or Middle-Eastern clothing. It is subtitled in Swedish and a hat is frequently seen floating between the characters' heads.
In 1984 the Lebanese musician Azar Habib recorded "Habbeetik" (in Arabic). Sixteen years later, Patrik Nyberg, Johan Gröndahl and Pet Bagge noticed that the lyrics not only sound like Swedish but also describe a popular drinking game involving the passing around of hats. In turn, they made a flash animation taking advantage of this fact.
Without changing the music at all, they proceeded to imbue Swedish wording to the song's lyrics such that their subtitles would match how a Swede would interpret the lyrics. It goes without saying, then, that the Swedish text is somewhat nonsensical. The original page, http://come.to/hatten, has been taken down, but mirrors survive.
