Eugene signs the telegram "You're brother Eugene," making the all-too-common mistake of confusing "your" and "you're."
Monk: Now return to your sisters.
Buttercup: Thank you, master!
Monk: Oh, she's a good kid.
Professor Utonium: So, where's that crazy brother of mine?
Doctor: Are you proud of yourself, young lady?
Buttercup: I.. I...
Doctor: Thanks to you, he can't eat right, he can't talk right, and he can't even think right.
Buttercup: No! No! NNNNNNOOOOOOO!!!!!!!!
Blossom: What got into her?
Chubby Guard: Oh, yeah! One more thing: this guy is nuts over taffy. He goes crazy for the salty-sweet tang. So, whatever you do, do not let him near any taffy! Got it? (Leaves)
Scrawny Guard: (Opens lunchbox) Boy, did I pick the wrong day to start my all-taffy diet.
Professor Utonium: There's a scientific exposition at the Townsville Convention Center, and you're looking at the keynote speaker. I'm giving a presentation of the proliferation of subatomic particles on the ribonucleic plane, and its relationship to the proliferation of ribonucleic particles on the subatomic plane.
(Powerpuff Girls just stare)
Professor Utonium: Oh, it's really quite fascinating, isn't it?
(Powerpuff Girls continue to stare)
Narrator: Meanwhile, back in... the city of Townsville... Professor Utonium is getting ready for a very big day.
Bubbles: Whatcha doing, Professor?
Professor Utonium: Well, Bubbles, I'm getting ready for a very big day.
Narrator: The city of... Longville, Minnesota! The turtle-racing capital of the world!
Buttercup: What should I do, Master?
Monk: The water rushing down the mountainside washes away impurities and replenishes the land. You must be like water, grasshopper.
Monk: Kick his butt!
Mojo Jojo: Oh, no!
Mojo Jojo: (To Buttercup) Girls are stupid. (Runs, then comes back) I'm smarter than you. (Runs, then comes back) You cannot defeat me. Green is not your color. You look fat in that dress.
Monk: The path will not be easy.
Buttercup: I'm ready.
Monk: Only the most serious mind can -
Buttercup: That's me!
Monk: You must look inward.
Buttercup: Get on with it!
Monk: You must be patient, grasshopper.
Buttercup: Oh, sorry.
Buttercup: You don't even know what my problem is. How can you -
Monk: Grasshopper, be not violent or angry, for peace lies within.
Buttercup: Yeah, yeah. I get that a lot.
Buttercup: I need to change, and I don't even know where to start.
Monk: At the beginning, grasshopper.
Buttercup: What the - who? I'm not a grasshopper!
Bubbles: You have been taking your fighting a little too far lately.
Blossom: Yeah. You didn't have to beat the stuffing out of Fuzzy so badly.
Bubbles: Poor Fuzzy!
Buttercup: Hello?! He's a stinking bad guy, remember?
Blossom: What's yours, Buttercup?
Buttercup: (Reading fortune cookie) "Be not violent or angry. Peace lies within." What a stupid fortune! It wasn't even funny.
Blossom: I don't know, Buttercup. Sounds right to me.
Bubbles: Me, too.
The Narrator mentions Longville, Minnesota in "Say Uncle." In reality, there really is a Longville, Minnesota, located southeast of Leech Lake in the north central part. It's nicknamed the "turtle-racing capital of the world."
The Girls' fortune cookies say the following:
Bubbles - "You bring sunshine to all who surround you."
Blossom - "Your quality is that of a leader, others are sure to follow you."
Buttercup - "Be not violent or angry. Peace lies within."
Buttercup learns not to overdo things in "Makes Zen to Me."
It's revealed that the Girls have an uncle named Eugene.
Villain(s): Fuzzy Lumpkins & Mojo Jojo.
Professor Utonium: I'll be coming on the last train on to Clarksville.
"Last Train to Clarksville" was a hit song by The Monkees in 1966 that, in reality, actually debuted before the show did.
Zen Master: Various
The Zen Master calls Buttercup "Grasshopper"; this was the name that the hero's sensei named him in the classic adventure series Kung Fu, and the later sequel Kung Fu: The Legend Continues.
