> This gets extra fun when you have a product which is actually named "My Card" (which, of course, is a bad idea to begin with, but...). Is it "Your My Card" or "My My Card"?

Japanese use of "my" as a loanword creates a lot of these. Please park your my car in our my car parking lot.

One would think those uses of "my" are limited to small stuff people don't pay attention to. But no, the gov pushed a "My Number" card initiative that acts as an official ID and is pretty critical to many procedures, including health insurance.

So you're at the counter with the clerk going "Please show me your My Number card".
