A Mars Bar (snazzy name) party... on Behemoth's acre of Mars! Great idea!! (Would you mind?) It would be epic. We could play Martian games (well, Metroid games ) and tell scary Martian stories and watch the Martian moons rise. That's officially now on my "list of things to do before you're seventy" - eat Mars Bars with my fellow Martians on Mars! What could be better?
If nobody owns Mars, who better to claim it? That's essentially what America did with the "unexplored" Wild Wild West (although there were people there, and they had to fight... more like forceful stealing in that case... just make sure your acre doesn't have a Martian's home on it and you're aok). But there aren't any people on Mars (except Martians) so I'd recognize your £16.00 acre, if we ever get around to going to Mars to begin with.
Yeah, they're everywhere in England still. Maybe not so much an American thing? But you have Twinkies, and we don't, and that more than makes up for Mars bars.
And Nuju, eating Mars bars is fine, but the way they're eaten at those parties is what puts me off.
