How about an open-ended question: What's your most embarrassing computer-related moment?

I'll go first:

I was messing around with .htacc files (as the webmaster of a small but fairly important website within the organization) and I saw a line that was commented that had something about having your own "custom" error page. Just to see if it would work, I put in

http://www.homestarrunner.com/error

For some reason, I left it in there and my boss called me into his office a few weeks later and said someone had called him asking about some strange error message they had gotten.

No real way to talk yourself out of that one.
