Your #1 is a good point. Since the only value of this "product" is that it's a joke, the number of "likes" he got in different countries could just be a reflection on how funny people from different cultures think "virtual bagels" are, and not an indication of any commercially significant behavior.
Or, users in the U.S. might just be so jaded from having seen too many joke products advertised on Facebook that they don't bother liking them anymore, while they may still be a novelty in Egypt.
Or rather than making tortured assumptions that Egyptians are especially tickled by VirtualBagel, you could use Occam's Razor. It is more likely that "Ahmed Ronaldo" is an indiscriminate clicker than that some obscure aspect of Arab history makes Virtual Bagels especially more funny to Egyptians than to Brits.
