No one should feel too smug over the whole Martian landing thing - Belgians just got taken in by a similar thing:

Suddenly and shockingly, Belgium came to an end. State television broke into regular programming late Wednesday with an urgent bulletin: The Dutch-speaking half of the country had declared independence and the king and queen had fled. Grainy pictures from the military airport showed dark silhouettes of a royal entourage boarding a plane.

Only after a half hour did the station flash the message: "This is fiction."

It was too late. Many Belgians had already fallen for the hoax.
