A common one in Referenced by...: William Shakespeare. Just like in the original context, it's used at the death of a young man; though the variation "good night, sweet princess" is occasionally used for women.
As this phrase borders on Narm at the best of times, twists and parodies vastly outnumber the dramatic use.
