Writing the two words, "The end," on the last page of the last chapter, is always a "happy ending," no matter what happens. Intrigued by what others had used as last lines for their happy endings, I did a little research and came up with some I thought were great. In fact, I might have to steal one or two for my next book--and write the story beginning with "the end"..."
"Now, where was I?" - Memento
"That was one kick-ass party." - House on Haunted Hill
So what are your favorite last lines?
