Pinky and the Brain usually ended with this exchange, or a slight variation on it:
: "Let's get back to the lab and plan for tomorrow night." Pinky
: "Why, Brain? What are we going to do tomorrow night?" Brain
: "The same thing we do every night, Pinky: try to Take Over the World
- Here are some of the slight variations:
"try to take over the world from Joyce DeWitt!"
"try to take over Chia World!"
(in an episode that takes place in Shakespearean
times): "try to take over the Globe...Theater!
(in a tongue twisting episode) "try to wake over the torld!"
(in a Very Special Episode
where the Brain gets hooked on cigarettes): "* coughs* try to quit smoking. Hand me that Nicorette patch."
(in episodes where Pinky and the Brain actually have to save
the world from Brain's Arch-Nemesis
): "The same thing we didn't
do last night, Pinky: try to take over the world!
(in the episode where the Brain gives sentience to the Earth) "Well, there's one thing we can do: try to take over the moon!"
(in Wakko's Wish
) "plan for the sequel where we'll take over the kingdom and the world!
(in which the Brain suffers a Never Recycle Your Schemes
What now, Brain? Back to our mushroom house to prepare for tomorrow night? Brain:
No, Pinky. We shall stop at a pharmacy and purchase a tube of denture adhesive and then attach our bodies to the bottom of Air Force One
So we can take over the world? Brain:
No, it's just fun, fun, silly-willy
(in which the duo become popular children's show characters in The Fifties
Come, Pinky. We have work to do. Pinky:
You mean taking over the world? Brain:
No, Pinky. Finding a good hiding place.
(in which the Brain tries to create a story about himself as a folklore hero)
Pinky: What are we going to do tomorrow night, Big Crabby See-Saw Kwanzaa Hot Mutton Chop Zekenote ?
Brain: Work on learning each other's names, and then... try to take over the world!
(last, but not least, in a rare daytime episode involving their "day jobs" as lab mice in mazes): Brain
: We must prepare for tomorrow morning. Pinky
: What are we going to do tomorrow morning? Brain
: The same thing we do every morning, Pinky: run through that stupid maze.
- And of course, there's the subversion in the episode "Ambulatory Abe":
Brain: Come, Pinky, we must—well, you know.
- There's also the trademark voiceover ending of "They're dinky, they're Pinky and the Brain, Brain, Brain, Brain, Brain..." just before the end credits music. Certain episodes change this slightly in either the wording or the delivery. The Halloween episode had demon voices saying it followed by Pinky's Catch Phrases and the Devil yelling "Stop that!"
