Both from Monty Python and the Holy Grail
Lord: Look, it's quite simple. You just stay here, and make sure he doesn't leave the room. Alright?
Guard: Oh, I remember. Ahh can he leave the room with us?
Lord: No... you just keep him in here, and make sure...
Guard: Oh, yes. We'll keep him in here, obviously. But if he had to leave and we were with him...
Lord: No, just keep him in here...
Guard: ...Until you or anyone else...
Lord: No, not anyone else. Just me.
Guard: Just you..
Lord: ...get back.
Guard: Get back.
Lord: Right?
Guard: Right. We'll stay here until you get back.
Lord: ... and make sure he doesn't leave.
Guard: What?
Lord: Make sure he doesn't leave.
Guard: The Prince?

The Holy Hand Grenade
Then did he raise on high the Holy Hand Grenade of Antioch, saying, "Bless this, O Lord, that with it thou mayst blow thine enemies to tiny bits, in thy mercy." And the people did rejoice and did feast upon the lambs and toads and tree-sloths and fruit-bats and orangutans and breakfast cereals ... Now did the Lord say, "First thou pullest the Holy Pin. Then thou must count to three. Three shall be the number of the counting and the number of the counting shall be three. Four shalt thou not count, neither shalt thou count two, excepting that thou then proceedeth to three. Five is right out. Once the number three, being the number of the counting, be reached, then lobbest thou the Holy Hand Grenade in the direction of thine foe, who, being naughty in my sight, shall snuff it."
