Yes, it's Zac Efron and Vanessa Hudgens. But, if you can imagine they aren't there, the rest of the video is very, very funny, or you die. Wow, that's a lot of pressure for each video. I wonder who makes the decision whether Zac was funny or should die. Maybe Will Ferrell? Yeah, I think he makes the decision. First he dresses up as Mugatu and then he watches the video and decides if you are funny or if you die. So far, it has just been extras that have been killed. No one really misses them or notices they are gone. Anyway, here is the video.
