(WIRED)  -- Who says Facebook founder Mark Zuckerberg has no sense of humor when it comes to "The Social Network," the Oscar-nominated film which he has said got nothing right except his T-shirt collection? Zuckerberg made a very sporting cameo tonight on NBC's "Saturday Night Live," running lines with guest host Jesse Eisenberg and SNL player (and frequent Zuckerberg "impersonator") Andy Samberg, during the show's opening monologue. As Samberg and Eisenberg -- Oscar-nominated for his portrayal of Zuckerberg in "The Social Network" -- bantered on stage, the camera cut away to the real Zuckerberg in trademark T-shirt and hoodie off stage with show producer Lorne Michaels.

"I wear this sweatshirt and I say, "I am @placeholder," Samberg shared.
