ER, Season 13

[Luka and Abby discuss a name for their soon-to-be-born son.]

Abby:
We don't have a name.

Luka:
I was kind of hoping we could name him after my father.

Abby:
Really?

Luka:
Yeah. He would really love to have a grandson named Mongo.

Abby:
M-mongo?

Luka:
Yeah, it's a very popular name in Croatia.

[Luka grins, and they both laugh.]

Luka:
I'm just kidding. My father's name is Josef. I don't care how we're gonna call him.
