Steven, The Doctor and others in “Galaxy 4”

Steven

Hey, you know, there might be a lake or a river around, Doctor. Do you fancy a swim?

[annoyed] My dear young man, this isn't a joy ride! This is a scientific expedition!

Steven Taylor

Oh, come off it, Doctor! You can't be scientific all the time. Anyway, uh, you look as if you could do with a good wash-down.
