"What the fuck is a TARDIS?"

I am so pleased to start this conversation, and then it devolves into "Do you know who Doctor Who is?"
Her: "Doctor Who?"
Me: "yes, Doctor Who."
Her: "wait, what are you saying?"
Me: "Doctor Who is a show."
Her: "But who? I can't understand you."
Me: "It is called Doctor Who - that is the name of it."
Her: "I think I am not understanding you. Just email me about this."

Fun fact: my personal emails from my iPhone and iPad say "Sent from my TARDIS" instead of "Sent from my iPhone." Not where she saw it.
