What's the best way to prank your metalhead little brother? How about completely make over his room into that of a Bieber-loving teen girl?

Sometimes, on quiet afternoons at Twitter HQ, a guy in a letterman jacket will start a flash mob.

While it seems as though Saturday Night Live is losing some of their heavy hitters (and going into the dreaded lull of a rebuilding year), that didn't stop them from putting together a celebratory milestone clip for their 100th Digital Short, which features the likes of Justin Bieber, Justin Timberlake, Natalie Portman, and Jon Hamm. If this is going to be Andy Samberg's last hurrah, at least he's going out with a bang.
