[Baron Munchausen]

There was a proposal to spread some sort of pigment (probably plain old charcoal) across the face of the moon and turn it into a gargantuan billboard a few years back. Fortunately, this is too expensive and difficult to do for now. I don't know the technical details of this new 'patent' but implementing it is almost certainly too expensive/difficult as well. At least for now, we are safe.

If we ever reach the point where someone actually does something like this it will hopefully produce a huge negative backlash, possibly destroying the brand stupid enough to use it, and we won't see any more.
