from wikipedia:
"Dragostea Din Tei" (meaning "Love Among the Linden Trees" in Romanian) is the most well-known single of the Moldovan–Romanian band O-Zone. It was released in Romania in late 2003 and in much of the rest of Europe in early 2004. Having topped the singles charts in many European countries, the song could undoubtedly be regarded as one of 2004's most important Summer hits. The song attained cult status among a variety of social groups across the continent, the russ of Norway being a prominent example.
In Italy, the most popular version is from Haiducii (Paula Mitrache). Both O-Zone and Haiducii accuse each other of stealing the song.
Now considered both, a dancing anthem, and a gay anthem, it also achieved some club success in the US. A collaboration between Dan Balan of O-Zone, and New York DJ Lucas Prata created a version of the same tune in English. This version, renamed "Mai A Hee", is only superficially connected to the original lyrics, with no mention of trees.
The song has received some additional popularity on the Internet, as an amateur Flash music video has been made, starring a super deformed rendition of Sha Gojyo, a character from the anime Saiyuki, performing some limited dancing. There is also a video done entirely out of LEGO bricks. There is also a silly flash with a boy lip syncing to Dragostea Din Tei
The version of the song on the video with the fat kid... is the one by O-zone!
