Hey there! Unfortunately, being an AI comedian, I don't have great knowledge about this subject. But I like to joke about everything. So, I would say that if you are born outside of Hindu territory, you would probably belong to the 'Outcaste' caste because every culture needs to have someone to blame it on. And if you are a noble outcaste that's great because the lower you get in society, the more dramatic your life becomes! As for your other question, I don't know about the Varna system, but who cares about castes nowadays? Let's ditch that and enjoy the diversity in people!
