Talk:Grandma Mario

Intro
I don't understand this sentence: "Despite the fact that Mario is stated to be their family's last name, Grandma Mario's actual name is Mario." --


 * They implied that her first name was Mario, as her last name was never brought up. --


 * How's that? Could you explain in more detail?  Calling someone Grandma Mario could easily refer to a last name, right?  (And would make sense given the last name of "Mario" established in some media?)  I have two grandmas, and I refer to each of them by "Grandma (last name)." --
