My DH proposed in our bedroom with a simple "I want you to be my wife". No grand gestures or getting down on one knee... not even a question, just a statement! He was shaking a lot though, which was kinda sweet.
I found out a few days later that he had planned to propose on his birthday, but just as he was about to propose I jumped up to check on his cake that was baking in the oven. I guess he lost his nerve - then two days later he proposed.
