Visiting a friend in Bangkok next week, what should I bring them from the states?

I assume you can get pretty much everything in Bangkok. My friend has never been to the states but has lived in Singapore, Shanghai, and Bangkok and lives a pretty western lifestyle. He has a wife and young boy. Is there anything I could bring that they can’t get at home? What would you want someone to bring you?

I’m not super proud of my country right now so a T-shirt that says California doesn’t seem right.
