1. "Over one billion" - the current number is around 1.1 billion, so if my napkin math is correct that's 1,100,000 x 0.66 = 726,000. Close enough for the girls I go with.

2. If you've ever learned a foreign language, especially in primary school, one of the first things you learn are nursery rhymes. I remember my French professor singing Frère Jacques to the class on day one of college.

3. Pretty much every country in Central and South America and a few islands in the Caribbean speak Spanish. They don't speak the same Spanish dialect as Spain, nor do they generally speak the same dialect as countries that border them. Languages evolve, and language alone doesn't typically inform things like nursery rhymes, culture does.

So congratulations, you're ignorant in three different languages.
