We’re not really sure whether this one passes the irony test, or, failing that, whether it passes for clever or super-stupid. As the entire message is, in fact, written in stone, it proves itself wrong and thus pretty pointless . . . but then again, the word “nothing ” is written in stone right here, so if read literally, the statement is technically correct . . . and pretty pointless.
All we can say for sure is that there’s somebody out there with a chisel and way too much free time.
