I think it was in Gnome (maybe still is), where you could use the ALT+F2 keyboard shortcut to bring up the run dialog, and type in "free the fish". And a swimming fish would appear across your screen. You could click on it and it would swim away, but would return a few moments later (unless you killed gnome-panel). We used to do it to each other if we left our machines unlocked.

I don't recall saying that.

Strangely, there don't seem to be many comments on the subject of "Heartland Institute Threatens To Sue Anyone Who Comments...".

Isn't this exactly what VGrep was designed to sort out?
