I was 12 and sitting in a movie theater with one of my best friends. After we came out, we started fighting. The movie was Star Wars and the fight was about who would get Princess Leia. My friend was so sure it would be Luke Skywalker. I thought Luke was a goody two-shoes and insisted on Han Solo to be with her. We all know who won in the end.
If I asked you, what quote from the movie springs to mind first, you would probably choose this one. It has been altered for parody many times and it's a classic. "May the force be with you." The other day I almost said it to my boss when she left for a stressful meeting and I use it if someone has to tackle a difficult task.
