Justin Timberlake and Jimmy Fallon are unstoppable. They rolled out another skit last night (JT is on every Tuesday this month to promote the release of his album "The 20/20 Experience Pt 2"). This skit shows what it would be like to use hashtags in real life. On Twitter they're annoying, in real life, they make for a funny video. Let's hope this doesn't catch on #Hashtags.
