Kanye West has been showing up in all sorts of random places including LeBron James’ NBA announcement, alongside King Tut’s great-grandmother, and now the Facebook headquarters. Mr. West, in a designer suit, stopped by the social networking website’s Palo Alto, Calif., offices on Tuesday (July 27) to perform four songs from his fifth album, including “Mama’s Boyfriend,” “Lost in the World,” “Chain Heavy,” and “Sweat on My Face.” Watch him entertain atop a cafeteria table below.
