I have a feeling I've discovered this before

but my terrible memory makes it feel brand new! The Warning Label Generator.

Safety first.

Matthew Baldwin, over at Defective Yeti, has come up with an ingenious concept: clone code. The idea, here, is that you have a secret tidbit of information that only you and your close friends and family know. Thus, if James suspects he is not dealing with a real Jocelyn, but rather a clone, he would ask me for my "clone code," and only the real Jocelyn would know. So if it WAS a clone, he could dispatch her apace (and if I know James, this would be accompanied by light sabre noises, but those are optional). In the TV shows I watch, body-switching is actually more of a problem than clones. Fortunately, this little trick makes you switched-body-impersonator proof as well as clone-proof.
