There is a craze in the United States of what I am calling the "Numa Numa Phenomenon".
It was started innocently by this regular guy, Gary Brolsma, who created a video of himself lip singing to the song "Dragostea Din Tei". The phenomenon is the numerous parodies spreading around the Internet of what Gary had started.
You can check out a collection of these video parodies on YouTube.
Here's a bit of background about the song, "Dragostea Din Tei". It was originally released in 2003 by a Romanian group called "O-Zone" in Romania and then 2004 through out Europe. It became the best selling single of the year (2004) in Europe.
In Japan the song was remade, dub with Japanese and English words and re-released as "Maiahi". Since its released, it is still on the Japanese Top 10 charts. A Flash version was made by Avex using the famous Japanese character MonÄ as the promotion video for the Maiahi CD. Although Avex refused to admit that their character was the actual MonÄ.
This song is so popular worldwide, artists from around the world have recorded their localized versions of the song. Including Italian, German, Spanish, Brazilian, Dutch, Afrikaans, French, Russian and Hebrew.
Of course with the release of Walt Disney Pictures' "Chicken Little" in the United States, I am sure this song will break even more records (excuse the pun) as theatre releases happen around the world.
