When characters breathe their last

The final words a character speaks are often their most compelling. What are your favourites?

I have been thoroughly enjoying this site's discussion of great opening lines. Thinking about first lines made me think about great closing lines - and then about the great "last words" of fictional characters.

Which got me thinking about tragedy, and reminded me why I left the execrable Stratford production of King Lear at the interval. I don't usually walk out on plays, and I have nothing against Sir Ian McKellen taking his clothes off, but I was dismayed by a couple of hours of theatre where potentially moving and profoundly serious moments were, lazily, played for Carry On laughs
