Jimmy Fallon And Justin Timberlake #Hashtag! [VIDEO]

I had a friend show me this YouTube video the other day, and I could not stop laughing! 

First of all, I will admit I really never understood the idea of hashtags. I do understand if you click on the #, it will bring you to others that are talking about the same thing. Like for example, SVU was on the other day, and #SaveBenson brought you to more information about the show and what others were saying about the show. That makes sense.

With that said, I can never understand these people that use it for the entire conversation.  To me it looks stupid. Watch as Justin Timberlake and Jimmy Fallon show you just how dumb you look only speaking in hashtags!
