I always wondered why this site would let you add and edit a signature but from what I've seen there has never been a "remove this signature" option. If you do actually try to remove everything then no changes take effect at all. Instead it forces you to insert stuff that isn't funny or doesn't make sense... like stuff Confucius would say or stuff from bash.org

Well in order to "get rid of a signature" lets say instead you've found out that you can use bold tags in between a " " <- (space without quotation marks). Thats nearly eight or so bytes worth of junk for a line at the bottom of your posts which is no longer needed or wanted for that matter.
