I included a handful of quotes in 'The Little Dustbuster That Could', so if you haven't spotted them all, they're under the cut.

I like bananas. Bananas are good. Lots of potassium. From new Who, Nine, either The Empty Child or its sequel.

There's no point in being grown up if you can't be childish sometimes. I thought this was new Who, but Turloughishere, who knows this stuff, tells me it was Tom Baker's Doctor.

"I don't know why I like you so much."
"Because you have such good taste."
"That's true! That's very true." also new Who.

You [humans] have an amazing capacity for self-deception. Ditto.

I ought to have given myself more warning Old Who. I don't know details, but in my head, it's Tom Baker's voice.

"Must be a spatio-temporal hyperlink."
"What's that?"
"No idea. Just made it up. Didn't want to say 'magic door'." (Or, in this case, 'magic dustbuster'.) Ten, 'Girl in the Fireplace'.

Don't even get me started on that movie! plus the DeLorean reference, doing double duty as SGA and Back to the Future.

And of course there was JC, who takes time travelling dustbusters in his stride: "It's, like, Time And Relative Dimensions In Space, or something," he commented. Everyone spotted that, right?
