I could spend hours here: Last Words, a site that indexes and explains the famous last words (both real and supposed) of real and fictional people. I've only read one page, but I am enthralled already. Some are inspiring, while some are just plain funny. For example:

Hilton, Conrad N. (1887-1979)

"Leave the shower curtain on the inside of the tub."

Conrad Hilton was born in San Antonio, New Mexico, and began his career by renting out rooms in his adobe home. He took a job as a local bank cashier and was so successful that he soon purchased a bank of his own. He assumed control of a small hotel in Cisco, Texas, in 1919 and over the next sixty years built an international hospitality empire. On his deathbed just before he died, Hilton was asked if he had any last words of wisdom for the world.
