Quinn: Oh my God...are you proposing? We've known each other for 6 weeks. Stand up, you're freaking me out.
Sam: I want to marry you...someday. Until then, will you accept this promise ring?
Quinn: What are you..six?
Sam: If you accept, this ring will symbolize my promise to you...to be true, to never pressure you to do anything more than kiss. To listen to your problems, to tell you when you have food in your teeth..or eye gunk. To come over to your house whenever you need something super heavy moved around. I promise to make you feel proud when you point down the hall and say, "that dudes my boyfriend".
