By now, you've probably seen this incredible version of Celine Dion's "All By Myself" recorded by a guy stuck (alone) in the Las Vegas airport. But it's not the first time someone won the Internet by lip synching.
Here are our five favorites.
"I Want It That Way" –– Backstreet Boys (2005)
Using a low quality web cam in their dorm room, the Back Dorm Boys, a Chinese duo, recorded this version of the Backstreet Boys classic.
"I Want It That Way" - Backstreet Boys (2009)
A different take on the same song, five office dwellers (and one stick-in-the-mud) show us just how fun work can be.
"I Gotta Feeling" - Black Eyed Peas (2009)
In 2009, schools began challenging other schools to lip dub contests. This version of the Black Eyed Peas party classic – performed by dozens of students, all over the school – went viral almost immediately.
"You Make My Dreams" - Hall & Oates (2009)
Different school. Different song. Same awesome result. And they did it in reverse.
"You Bring Me Joy" - Anita Baker (2009); "Can't Tell Me Nothing" - Kanye West (2009); "Not About Love" (2009) - Fiona Apple
Whether he's covering Baker, Kanye or Fiona Apple, Zach Galifianakis' music videos are always fresh, funny and memorable.
