The Doctor and Amy in “The Time of Angels”

Amy Pond, you are magnificent, and I'm sorry.

It's okay, I understand. You've got to leave me.

Oh, no, I'm not leaving you, never! I'm sorry about this! [bites her hand. Amy yelps] There, see? Not stone, now run!

You bit me!

Yeah, and you're alive.

Oh, I've got a mark, look at my hand!

Yes, and you're alive! Did I mention?

Blimey, your teeth, have you got space teeth?!

Yeah, alive, all I'm saying!
