Well, at least Sophie gets it right. If she's his wife, she married an idiot. Or at least an ignoramus.

Perhaps it's not so surprising:

Well of course that's what they'd say. Aren't the French told from birth that the entire Universe revolves around them?

I wonder how Americans would do? Sadly, probably not much better.

The fact that the audience helped him get it wrong is priceless.

Now we know why the French don't have a secret moon base :-)

I'm not sympathetic, but the French question was "Qu'est-ce qui gravite autour de la Terre?" and the French infinitive "graviter" means, "to gravitate". The preposition "autour" is ambiguous, having contextual meanings including "about", "around", "at the", "to the", etc. If someone asked you "What gravitates at the Earth?" your natural response might be "What the hell are you talking about?" -- but on a game show like this you can't object to the questions. You might easily convince yourself that if they meant the Moon, they would have asked "Qu'est-ce qui orbite autour de la Terre?" Maybe this video says as much about the idiot French questioners as it does about our hapless victim and audience.
