Brazilian jiu jitsu Puns

My wife and I have a friend coming over this afternoon and he's bringing his new girlfriend that we haven't met yet. We know she's Brazilian, so I asked my wife "do you think she knows jiu-jitsu?" with that dad-joke look on my face because I was proud of my accomplishment. My wife responds without hesitation with "nope, she's not a Jew" and all I could do was shake my head with disappointment that I'd been outdone while being so proud of her at the same time.
