( CNN ) -- An NBC sports announcer was playing the classic game of spot-celebrities-in-the-stands during the gold medal Olympics match in men 's basketball when this happened : . `` I know I 'm gon na put that picture on Facebook , '' Bob Fitzgerald said as the camera showed a young man with curly hair and a red hat , according to a video posted on the blog Deadspin . `` We 've got every executive of note , it seems , worldwide , attending these Games . '' The problem : The man in the audience was n't Facebook co-founder Mark Zuckerberg . It was the actor , Jesse Eisenberg , who played him in the Academy Award-winning movie `` The Social Network . '' Olympics viewers outraged after NBC cuts away . Oops , right ? Well , the Internet wo n't quite let a gaffe like that pass without some dissection . `` Hey ball announcer : that was Jesse Eisenberg who played Marc Zuckerberg in a movie . He did n't create Facebook . # Olympics # NBCfail '' one user , Mike Sigmond , wrote on Twitter . `` The Eisenberg Principle - When you are absolutely certain that you 're looking at Mark Zuckerberg but it 's really Jesse Einsenberg . # NBCFail , '' wrote Sandy Sternshein . Another wrote that it was a `` buzzerbeater # NBCFail for the Olympics . '' It was just another reason to revive what has been the omnipresent # NBCFail hashtag during the London Games . That meme mostly has been used by Americans who have loved to complain about the fact that many of the 2012 Olympic events were shown in the United States on a tape delay . But maybe there 's something a little more interesting going on here : Sports announcers make mistakes all the time . Sure , it 's live TV . But in the same way that the comedian Tina Fey sort of became Sarah Palin during the 2008 U.S. presidential race , Eisenberg became a sort of stand-in for Zuckerberg 's real persona , particularly right after that movie debuted . ( To make things all the more confusing , the pair appeared together on Saturday Night Live . ) At the time , at least , some people seemed to know the fictional Zuck better than the real thing . Or perhaps that 's still the case . The man who started # NBCFail on Twitter .
