I too have noticed a lot of references to Turkey, Japan, China, and France, especially France. Not just because of Emily, but because I've noticed they incorporate the Eiffel Tower a whole lot, about as often as Albert Einstein, the only references to Germany that stand out to me. Kind of like how on The Dick Van Dyke Show, Rob, Buddy, and Sally the writers of The Alan Brady Show had used German professors too often in comedy skits.

Yeah, they do incorporate the Eiffel Tower a lot.

I've never watched The Dick Van Dyke Show, but that sounds pretty funny...like they're playing into a stereotype of some sort.

Anyway, as I've mentioned, the show makes quite a few references to the country and culture of Turkey as well, even outside of Adil's life...now, I don't happen to have a lot of Turkish friends, but many of my friends are Vietnamese, Indian, Korean, and Filipino. So while, in my community, at least, those four ethnicities/cultures greatly outnumber people of Turkish descent, I am surprised that they mention/show Turkey and its culture more often than they do those four countries/cultures combined. Perhaps they want to emphasize more obscure or less common cultures in the show?

I've also noticed that Mexico and its culture isn't mentioned very often in the series...surprising, considering how much Mexico is in the news and mainstream pop culture, and its being one of the countries that many people in the US are familiar with. Though Buster did visit Guanajuato, Mexico in PfB once.
