While hosting "Saturday Night Live," Zach Galifianakis covertly shaved his trademark beard.
The 40-year-old comedian slipped backstage while the show's musical guest, Vampire Weekend, performed. When Galifianakis emerged for the next sketch, his shaggy, reddish beard was gone, with a mustache in its place.
When Galifianakis returned to wave farewell at the end of the show, he'd changed yet again, donning a fake beard much like his original.
NBC posted a Web-only video on NBC.com and Hulu.com of Galifianakis rushing backstage and quickly shaving.
Galifianakis, who co-starred in "The Hangover," has often made his beard a focal point in his standup and has rarely shaved it. In a 2008 interview, he joked: "I would shave, but then I look like Jodie Foster."
