Raphael: [pause] Say what?

Michelangelo: See Don, we can have our very own Battle Shell. I've even got a name for it. I call it: "The Battle Shell"! I've got it all figured out. Turbo-boosters, double-action traction, cool secret thingies shooting out the back. We should be tricking out the armored car!
Donatello: By "we", you mean me. And I don't have the time. There's too much to do around here. Besides, where would we keep the thing?
Michelangelo: We could find a place. Just think of overhauling the wheels. Please? Please please please please? Did I mention you're my favorite turtle?

Splinter: Ahem.
Michelangelo: Busted!
Splinter: How many times have I told you not to sneak up to the surface?
Michelangelo: This month?
Donatello: 512, actually.
Splinter: It is dangerous for you to go about openly in the world above. You cannot simply walk amongst the humans. They will not accept who and what you are. It is as the great sage and warrior Kenji Hashimura once said, "Why walk when you can ride?"
Raphael: Come again?

Splinter: Young woman, we have something most important to discuss.
April O'Neil: What?
Splinter: We have never revealed ourselves to the other world. You have placed us all in great danger.
Leonardo: But, Master Splinter... she was in trouble and we helped her.
Raphael: Yeah, aren't you always teaching us to do the right thing?
Splinter: As you grow older, you will learn there are many ways to do the right thing. But there is no going back. I'm afraid we find ourselves at your mercy.
April O'Neil: Oh, I would never tell anybody. I mean, who would believe me?
Donatello: She's got a point.

Baxter Stockman: [turns on the communicator] What?
Oroku Saki: Dr. Stockman.
Baxter Stockman: Make it quick. I'm very busy.
Oroku Saki: I am contacting you to verify that you are fulfilling your end of our bargain and that you are on schedule.
Baxter Stockman: I will not stand for anymore of this idiotic interrogation! I've advanced the Mousers to the next stage, and they are securing the funds from the bank as you requested. Can you grasp that simple concept?
Oroku Saki: Do not presume too much, Dr. Stockman. The price for failure would be quite extreme.
Baxter Stockman: [Stockman turns off the communicator] Imbecile!
01x03 - Attack of the Mousers (2) Season 1 / Episode 3: - Attack of the Mousers (2)

Baxter Stockman: Intruders? Here to steal my secrets? You will leave here nothing not even your lives. [stares at the heat signatures of the Turtles] What on earth are you? I suppose I'll have to dissect you to find out.
01x03 - Attack of the Mousers (2) Season 1 / Episode 3: - Attack of the Mousers (2)

Baxter Stockman: [to the turtles] What are you?
April O'Neil: They're with me!
