Yesterday Facebook employee Morin Cynthia Oluwole, uploaded a video that she took while Kanye West performed his new “Chain Too Heavy” song at Facebook’s headquarters in Palo Alto. While many of the employees were slightly concerned that Kanye would jump off the table and drop his heavy chain on them, it looks like many were excited to have Kanye drop by the office. Nothing like an unexpected visit from a famous rap star, right? You can see a video of the event below.
