Another lede is being buried here; cutesy error messages are a pernicious form of escaping responsibility and liability. Which is to say, when you see this sort of thing as a user -- understand that in some form, whoever or whatever entity created the thing you're using doesn't care about you -- or more specifically, has no reason or incentive to treat you respectfully enough to be clear about the error.
