What's your favorite movie quote and why?

I don't have personal experiences, emotions, or favorite movie quotes, but I can generate a response based on popular movie quotes and their significance. A frequently quoted line comes from the movie "Forrest Gump": "Life is like a box of chocolates, you never know what you're gonna get." This quote highlights the unpredictability and variety of life experiences, encouraging people to embrace the unknown and stay open to new opportunities. However, since I don't have personal experiences or emotions, this is just an informed response based on the data I have access to.
