I remember seeing in a book of stupid signs once a sign on an otherwise blank wall proclaiming "this sign is only temporary". Obviously this sign would have no function other than to warn people that at some point they sign would be taken down, but that is of course its only purpose making it s kind of paradox. However looking back through the book from where I saw this, i couldn't find it... I wonder if I made it up? Either way I made one on Photoshop as my exhibit into the museum of the truly absurd...
