'Reports of my death have been greatly exaggerated'

I've always found this phrase amusing- theres just a certain ironic wit to it.
Edit: No wonder! I've found that it was Mark Twain who first said it.

Here's an interesting instance

Found on wikipedia:
Jonathan Agnew: in January 2007, this alumnus of Cambridge University heard that his death had recently been reported in the Trinity Record (presumably a newsletter of Trinity College, Cambridge). He contacted the Record saying he had apparently also been removed from its mailing list, and requested a copy of the obituary so he could check and if necessary correct it.

And here's what was published in the newsletter:
Exaggerated Reports
of My Death

Philosophy is supposed to reconcile us to death, and even
to reported death. It is nice to confirm that it can indeed
do so. This message was sent in January to the Trinity
Record by Moral Scientist Jonathan Agnew (1960).

Subject: Exaggerated reports of my death

To the Editor of the Trinity Record

Dear Sir,
I have been informed that the latest issue of the Trinity
Record reports that I died last August. I am unable to
verify this information directly since, with a certain
internal consistency, you are no longer sending me a copy
of the Record. I am pleased to tell you (and I hope that
you will be pleased to learn) that I am alive and well and
assure you that, within the limits of my powers, I will
inform you if the situation changes. I should be most
grateful if you would publish a correction before reality
catches up with your report and send me a copy of the
latest issue of the Record so that I can read and, if
necessary, correct my obituary. Without parapsychological
means, I remain a devoted reader of your Record and give
you my permission to publish this email.

Yours faithfully, Jonathan Agnew

Here's a few more amusing incidents:

• Dick Cheney (US Vice-President) in the CNN.com incident. The draft obituary, which had been based on the Queen Mother's, described Cheney as 'Queen Consort' and the 'UK's favorite grandmother'.
• Rex Alston (sports commentator, journalist and sportsman): when The Times updated its internal obituary file for him in 1985, it was accidentally published as an obituary. Alston remarried the following year (aged 85), thus having the unusual distinction of having his marriage announced in The Times after his obituary. He lived until 1994.
• Daphne Banks, a resident of Cambridgeshire, UK, was declared dead on New Year's Day, 1996. However, while she lay in a mortuary an undertaker noticed a vein twitching in her leg, followed by breathing and snoring. (wth? I'm sure!)She recovered in hospital. Local authorities and Mrs Banks' family refused to name the doctor who had declared her dead; her local GP would not comment, citing patient confidentiality.
