I guess my joke wasn't that obvious
Since you mentioned it though, you can maybe muddy the waters a little with a "min fuel" dec. I'm not sure what that actually means to a controller when they hear it, other than the book answer (can accept no undue delay, etc).....but in terms of handling, does it give you priority or not? If I understand it correctly, it does not, at least in a legally binding sense. But I have also seen it absolutely give priority handling on most occasions where I have heard it used. If there were anything close to a declaration of "minor emergency" I would say this would be it, specific to fuel related emergencies.
