Joe Biden finally joined the "Selfie Club." In only his fourth Instagram post, he took the selfie with a very special guest.
 
Just who is this mystery selfie guest?

That's right, President Barack Obama! This really should be called the "First Selfie," since it is the President. Also, aren't they never supposed to be in the same place at the same time if it can be avoided. They should definitely never be in the same car or selfie photo!
 
As you may know, Obama caught some flack for his behavior at the Mandela funeral when he was taking "selfies" with other foreign leaders.
