I can't explain this, and I'm not going to pretend that I can explain it, except to say that this splitscreen video of a group of fans executing an eerily accurate shot-for-shot recreation of three anime girls singing "Everybody (Backstreet's Back)" is one of the weirdest and funniest things I've seen this week. Admittedly, it's only Monday, but sometimes you just peak early.

Update: It appears that the anime video was generated from the live-action one using a program called MikuMikuDance. Which makes it... make... more sense?
