- Carmen shows amazing hutzpa by delivering Zack and Ivy's burgers to them on their Stake Out.
Zack: No way we're leaving a tip, then.
- "Hot Ice":
Carmen: Now you're dreaming.
- When the Chief finds Carmen herself inside ACME headquarters and initially thinks she is coming back for good:
Chief: Well, then, WHOA, STOP! Uh-uh, NONONONONO—the Hindenburg was bad, but THIS IS—Pat, I'll buy a vowel and a consonant, N-O—YOU ARE NOT SUPPOSED TO BE HERE, CARMEN!
[Carmen pushes a button, and a cursor appears on the Chief's screen]
Chief: No, no, you wouldn't do that, get that thing away from me, you wouldn't do that, Car—
[Carmen pushes the cursor on the Chief's mouth, locking it in a box, and then moves it into another direction]
Carmen: Sorry, Chief, but Zack and Ivy have foiled my plans one time too many.
- "Scavenger Hunt":
Zack: I'm a mere shell of the man I was before that horrible egg-sperience. ... Really, if you weren't so egg-stremely punctual, the yolk would have been on me.

He suddenly begins to stammer and look utterly confused.

Ivy: Ugh! One of these days you will find out you are not as clever as you think you are, Carmen Sandiego!
- Carmen uses pigeons to thwart Zach and Ivy. Ivy's response:
- "Follow My Footprints", despite being a bit of a Mood Whiplash given the plot of the episode:
Moe Skeeter: Uh, Lars, the painting's on the wall.
- Moe Skeeter and Lars Vegas trying to figure out how to steal Leonardo da Vinci's The Last Supper.
Lars Vegas: Right, so what do you need? Bolt cutters? Screwdrivers?
Moe Skeeter: No, it's on the wall.
Lars Vegas: Of course it's on the wall! This is a museum!
Moe Skeeter: No, it's a fresco!
Lars Vegas: [grabs Moe] It's a museum!
Moe Skeeter: No! The painting's a fresco!
Lars Vegas: NOOO! The painting's a da Vinci, you witless insect! So how are we gonna take it?
Moe Skeeter: We're not! It's a fresco! And that means it's painted on the wall! [Lars takes out a flashlight to examine The Last Supper] I told you it was on the wall.
Lars Vegas: Yeah, but who knew it was on the wall?

Carmen: Interesting costume choice, Ivy.
- Zack overhears Ivy and Carmen confronting each other, and dashes to assist his sister, only to see Carmen Sandiego running down the hallway. He jumps her and ties her up, only for "Ivy" to remove her wig and reveal herself to be the real Carmen Sandiego. The Carmen that Zack just nabbed was really Ivy in costume. Made even funnier by the earlier conversation that he overheard.
Ivy: And did you really think you were getting out of here dressed like that.
