I admit it: I'm kind of obsessed with Wikiquote.org, the quote database equivalent of Wikipedia. It's got all sorts of fun quotes, from authors to celebrities, movies to books, and I fully admit that I use it when I'm trying to find all those Great Quotes over at the PFS Book Club.
For today's prompt, we're going to use Wikiquote's Famous Last Word page.
Write a story based around a Famous Last Words quote. The quote should be said by a character in the story and it should play an important part in the story's characterization and plot.
The fun part is not so much writing the story, but figuring out which famous last words you want to use. I'm partial myself to John Dillinger's "You got me."
