In a somewhat similar vein, a friend of mine has this t-shirt (For anyone not hip to René Magritte, the text translates as "This is not a pipe").

I've tried to think of ways to make similarly confusing statements applied to objects without relying on references to "this" or "I" or such, but haven't found anything satisfying thus far. Certainly nothing with the same elegance as "'Yields falsehood when preceeded by its quotation' yields falsehood when preceeded by its quotation".
