Setting: Futuristic Earth. The TARDIS slowly appears on a street corner complete with sounds and flashing lights. The Doctor walks out, smiling happily as Donna walks out behind him.
Donna: Well, it’s pretty I suppose. When are we? (they begin walking)
Doctor: The fifty-first century, a time of free love and expensive crockery.
Donna: (laughs) The way Jack made it sound like everyone was sleeping with everyone else. I couldn’t work out if he was telling the truth or just trying to get into my pants.
Doctor: Knowing Jack, probably both.
Donna: But wouldn’t it get complicated? I know I wouldn’t be too happy if my mum started sleeping with my husband.
Doctor: (airily) Oh marriage is long gone, went with the gender binary. The downfall of patriarchy made sex so much less complicated.
Donna: Gender binary? Whadya mean? There are men and women walking around, same as always. (sweeps arm around at extras to prove her point)
Doctor: (laughs) The things you would see without the TARDIS translating.
Donna: You said it only translated alien languages. (slightly accusatory)
Doctor: Weeell (buying time). Life without the patriarchy is pretty alien to what you know. Give you lot an a0fe-hock team and you turn it into a nuclear family.
Donna: Stop showing off with your ave-ocks and show me what you mean.
Doctor: You won’t like it.
Donna: Show me!
Doctor: (shrugs) Don’t say I didn’t warn you.
The Doctor takes out sonic screwdriver and presses button. Close up on Donna.
Donna: Oh. My. God.
The Doctor smugly presses the sonic screwdriver again, his manner implying “I told you so.” He is then abruptly distracted by a fruit shop.
Doctor: Donna, did I ever tell you about the time I invented the banana daiquiri three centuries early? Always take a banana to a party; that’s my motto. Well, either that or-
Donna: You’re more bloody bananas than this planet!
The Doctor smiles guilelessly and scene ends.
