How Many Different Facial Expressions Did Justin Bieber Offer His Philly Fans?

This might be our new favorite video ever. It cycles through more than two dozen photos from a “meet and greet” at Justin Bieber’s July show in Philly, and as far as we can tell, it contains three distinct facial expressions:

1. Justin Bieber smiling. This appears in maybe three or four photos.

2. Justin Bieber half-smiling. This is maybe two more photos.

3. Justin Bieber with a dazed look on his face, perhaps trying to signal the photographer with his eyebrows, “Help! My childhood was stolen from me and now I’m trying to rock this unsustainable and altogether inappropriate ‘sexy’ character when, really, I can’t even grow a beard quite yet and oh, God, just make it stop.” Pretty much the rest of them.

Anyway, here’s a bonus question: What the hell music is playing over this slideshow?
