Copyright Battle Over Nothing
An Anonymous Coward writes: "In this story reported at The Independent is "one of the more curious copyright disputes of modern times." It appears that the key question is "which part of the silence was stolen." If only this was April First. This is a lawsuit suing over the sound of nothing, no sound, silence, nada, zilch, bupkiss.
Also keep in mind this piece was premiered in an open air theatre in the forest. There would likely have been much more than silence heard.
And this isn't even getting into the idea that it is impossible to actually hear silence.
Welcome to Slashdot, where Copyright == Trademark.
It even says on the page you linked: "'Have Fun!' is a registered trademark of Pat O'Brien's".
Which is still somewhat absurd, but they probably do have some legal ground - if some competing establishment tried to use "Have Fun!" as a slogan, it would justifiably be considered trademark infringement.
If the words "Have Fun!" really were considered a copyrightable work of literature, it would indeed be the most ludicrous copyright ever, so it's rather nice that that's entirely untrue.
