Justin Bieber was on The Ellen DeGeneres Show and she thought it would be fun if the two of them scared strangers. So they hid in the handicap stall in the ladies room to see how women would react to seeing them in there. Most of them screamed, and some of them screamed even louder when they realized their idol was right there in front of them.
Proving as loud as you scream when someone scares you, you scream even louder if you see finally get to meet someone you worship and idolize. Just hopefully when we the chance to meet said person, it is at a much better location like anywhere else.
