How should I reward myself for watching and taking notes on a movie I totally don't want to watch?

I can’t bring myself to watch and take notes on a 2 hour long teaching movie on the human anatomy but I really need the extra help since I’m just a half notch above mentally retarded. How should I reward myself for following thru on watching the movie, so I get inspired to watch it? (yes, it’s Saturday night and I’m doing homework. ‘Nuff said.)
