Cameo: Kryten has appeared before, because whenever I hear “So what is it?” my brain goes into that sketch from Red Dwarf.

Narration: It was a long line.

Yumiko: Enrico?

Enrico: Yeah?

Yumiko: I’m nervous…I’ve never been to a dance before.

Enrico: Oh, the masquerade isn’t a dance!

Yumiko: Really? So what is it?

Enrico: I’ve never seen one before.

Kryten: No one has…but I’m guessing it’s a white hole.

Enrico: So, um, your guess is as good as mine.
