The Twilight Saga: EclipseEvery time a 'Twilight' trailer debuts, there's an "eeeeeee!" heard 'round the world. Several "eeeeeeee!"s, in fact. So, that loud sound you heard on Thursday morning? That was the online premiere of the official 'The Twilight Saga: Eclipse' trailer.

Fortunately -- for the sake of their memories, their grandkids and, frankly, all of humanity -- many thoughtful Twihards take the time to film themselves reacting to the trailer when it hits. And they came through in fine style this time, with an astonishing array of near-hysterical 'Twilight: Eclipse' reaction videos that still have our ears ringing several hours later.
