BoJack:
[reads "Dr. Allen Hu" calling card] Oh, it's Hu, Dr. Hu!

Dr. Hu:
That's right. Dr. Hu, Dr. Allen Hu.

BoJack:
No, no, but I thought it was Who, like Doctor Who.

Dr. Hu:
Yes, that's exactly what it's like.

BoJack:

Dr. Hu:
Umm, I don't know. Who is it? [to Sarah Lynn] I'm s— I'm sorry, is this a joke? Is he telling a joke? 'Cause I just don't...

Sarah Lynn:

BoJack:
Seriously? Am I the only one who knows the extremely popular BBC science-fiction show about the time travelling Doctor who saves civilisations?

Todd:
Ah! Yeah, I know what you're talking about. Doctor Who!

Dr. Hu:
Yes?

BoJack:
No. Yes! Thank you, Doctor Who!

Dr. Hu:
Yes?

Todd:
I saw the one where she goes to the Wild West. The Cheyenne called her Medicine Woman.

BoJack:
What? No, that's Dr. Quinn!

Todd:
Who's Dr. Quinn?

Dr. Hu:
I most certainly am not.

Sarah Lynn:
Hu's not Dr. Quinn, Hu's Dr. Hu!

Todd:
I don't know!

Hu/Sarah/Todd:
Third base!
