I brought in "Talladega Nights" for the physics students to watch after they fnished their assigned reading since they finished the movie the teacher left for them. I just opened the case to put it into the DVD. And it's empty. Crap crap crap. And I was all prepared to tie in velocity, torque, centrifigual motion, etc. into the movie so that if another teacher or administrator asked why I was showing it to them, I could at least try to BS an answer.
