If you want to be the most unproductive human alive. Sit your little hiney in front of Youtube and watch all the trailer recuts.
My awesome coworker/partner in crime/ love for archery sharer friend "Abra" was a rockstar today and used the original and recut trailers to talk about tone and mood in her Language Arts class. She rocks.
Then she showed them to me. Where I then proceeded to shed a good hour of valuable time off my free time clock engrossed in these recuts.
