Twitter knows how to have fun at work: Stages Justin Bieber flashmob [video]

Just in case you think that working at a startup is all work, Twitter reminds us that there is fun to be had during the day.

Yesterday, some of the employees in San Francisco staged a dance flashmob #flockmob to the tune of Justin Bieber’s “Baby.” Even though I can’t stand the song, or Bieber, it’s great to see the team having a blast.
