Looking for memorable error messages

Ever gotten an error message that puzzled you or maybe even ticked you off?

No one likes an error message, but sometimes the error messages are in their very tone kind of insulting. For example, I came across this one:

The server understood the request, but is refusing to fulfill it.

OK, Hal. This message implies that there is a problem with a rogue server with an attitude problem.

In a cms I used to use I once tried to post-date a piece for publication and was given the error message, "The future has not happened yet." Wow, really? Thanks for that condescending news flash. I could have gotten that message in a fortune cookie.

So, just for a little end-of-the-week chuckle, post some of the most memorable error messages you've seen over the years. Maybe you've programmed a snarky error message of your own you'd like to share. If we get a good enough response, we can get Art to make a us a nice download.
