- Gwendoline: [sings] I don't know what it is about my figure and my style / Then when I walk around the passers by do smile / I lost myself in Kensington/about a week today / I asked a cabman my way home / And to me he did say / That's the way to the zoo / That's the way to the zoo / The monkey house is nearly full / But there's room enough for you / Take a bus to Regent's Park / Make haste before it shuts / Next Sunday I shall come and give you such a bunch of nuts
- The Doctor: Let me guess. My theories appall you, my heresies outrage you, I never answer letters and you don't like my tie.
- Ace: Don't you have things you hate?
- The Doctor: I can't stand burnt toast. I loathe bus stations - terrible places, full of lost luggage and lost souls. And then there's unrequited love, and tyranny, and cruelty.
- Ace: Too right.
- The Doctor: We all have a world of our own terrors to face.
- Ace: I face mine on my own terms!
- Nimrod: At the season when ice floods swamped the pasturelands, we herded the mammoths sunwards to find new grazing.
- Redvers Fenn-Cooper: Tricky things, mammoths.
- Gwendoline: I think Mr. Matthews is confused.
- The Doctor: Never mind. I'll have him completely bewildered by the time I'm finished.
- Ace: Let's ring out for a takeaway. Anyone fancy a curry?
- The Doctor: I know a nice little restaurant in the Khyber Pass.
