"Lip-dubs" is a genre of viral videos that's defined by someone on screen lip syncing to a song that's playing in the background. Numa Numa is the mother of all "lip-dubs."The video's creator and star, overweight and quirky Internet celebrity Gary Brolsma, taped himself singing along to Moldovan pop group O-Zone's song "Dragostea din tei." The combination of the incredibly strange song and Brolsma's weird dance moves made the video an instant Internet sensation that has spawned several imitators, but nothing beats the original.

Watching the Star Wars Kid is like driving by a car accident—you'd like to look away, but you can't. The video stars a reluctant and overweight French Canadian teenager who filmed himself performing light saber moves used by Darth Maul in the film Star Wars: Episode I - The Phantom Menace. Like a lot of viral videos, this one will have you howling while you're watching it but will make you feel bad when it's over.
