I found out that I have some Persian blood in me as well. Even some of the relatives of Hasan ibn Ali (ra) which is the progenitor of the Ashraf's were partially Persian. Some in recent times when it comes to the Sharif's of Makkah as well.
This thread reminded me of something funny. Football related.
There is an Iranian Arab football player by the name of Hossein Kaebi. He comes from Banu Ka'abi tribe of Khuzestan. Banu Kaab - Wikipedia, the free encyclopedia
Anyway Iran where playing UAE, and there is a black-Arab trouble making player of UAE called Ismail Matar. I guess he found out that Ka'abi is Arab and started insulting him heavily during the match. Almost fight broke out. This is the only video of it I could find, there was a lot more going on in the match though.
