Clyde and Paul in “Unfinished Business”

Clyde

If it wasn't for me, all these people, they wouldn't be here! I've saved them loads of times and they don't know!

Paul

OK... is this some sort of trading card thing?

Clyde

Don't you believe me?

Paul

No, no, I'm not saying that. It's just you and this Luke, the two of you, saving the world.

Clyde

You don't know what we've seen! Slitheen, Sontarans, we've stopped them, all of them.

Paul

You and Luke?

Clyde

You don't believe me, do you? Fine, I'll prove it to you!
