That's what I shouted today when, using Mingle in Firefox 3 beta 2, I was unable to open a card. Or, in fact, do anything other than view a list of cards. And curse. And click harder.

Noticing, then, that Firebug was helpfully indicating an error, I opened Firebug to discover this message.

Then, I shouted "I win!" for I knew that nobody else would top my crazy-ass error message this day, no sir.

There is no such thing as security through obscurity, but hilarity on the other hand…
