This may be the most teeth-clenching video I've ever watched. Just look at that photo. In one shot, you have Celine Dion next to Justin Bieber next to Usher next to Will.i.am next to Barbara Streisand in front of LL Cool J in front of VINCE VAUGHN behind JEFF BRIDGES. Excuse the all-caps, but WHY IS VINCE VAUGHN THERE??
