Wait... if the sticker's not there... how does one know the number to call?

And if the sticker is there, what possible purpose could it serve?

Herewith my working hypothesis: This is the sort of logical conundrum that James T. Kirk would spring on evil computers or robots on the original Star Trek. (They'd short circuit every time.) So the purpose of the Florida law -- if this is for real -- would presumably be to keep evil robots from taking up residence in the Sunshine State.

Of course, this could also be fake, but what fun would that be?
