Victory of the Daleks (S5:E3)
This was a wonderful bit of humor in this episode:
(Matt Smith as Doctor talking to a Dalek with a cute little British flag.)
Dalek: Would you care for some tea?
The Doctor knocks the tea to the floor yelling.
Doctor: Stop this! What are you doing here? What do you want?
Dalek: We seek only to help you.
Doctor: To do what?
Dalek: To win the war.
Doctor: Really? Which war?
Dalek: I do not understand.
Doctor: This war, against the Nazis, or your war, the war against the rest of the universe, the war against all life-forms that are not Dalek?
Dalek: I do not understand. I am your soldier.
Doctor: Oh yeah? Okay! Okay! Okay soldier, defend yourself!
(picking up a large wrench to bash the Dalek with)
Dalek: (while being bashed) You do not require tea?
