I was busy browsing through an orkut community forum when something went wrong with the orkut server and it couldn't deliver the pages to me. Instead of a boring, dull error message page, I was delighted to see the following:
"Bad, bad server. No donut for you.
Unfortunately, the orkut.com server has acted out in an unexpected way. Hopefully, it will return to its helpful self if you try again in a few minutes.
It's likely that the server will behave this way on occasion during the coming months. We apologize for the inconvenience and for our server's lack of consideration for others. "
I don't remember the last time an error message made me smile :-)
