What is your favorite viral video?

Tweet

With the proliferation of video blogging and sharing started by youtube, there are many videos that spread like virus and even made celebrities out of the videos' subjects e.g. Numa Numa, star wars kid, etc. My fave is an audition in "Bulgarian Idol" titled "Ken Lee", which is actually referring to a song "Without You" popularized by Harry Nillson, later revived by Mariah Carrey. How about you? What is/are your favorite viral video(s)?
