I had to reboot one of our servers to complete a configuration change, part of which involved changing/updating its host name. I sent e-mail announcing that X would be going down and coming back up as Y. A co-worker inquired whether I should wait until Sunday for the Y part.
This reminds me of my favorite Easter joke:
Q: What's this? [stand with your arms stretched out horizontally on either side, parallel to the ground, and let your head hang down]
A: A lousy way to spend Easter weekend.
