The Monarch: Tears!? Come on! You know that sick deformed freak! You know he was pounding his invisible meat!
Dr. Venture: Your honor, I have children here! I don't want them listening to this potty talk!
Judge: Order! I want that comment struck from the record. And my mind

Tiny Attorney: So... mind-reader... fascinating, could you read the mind of... say for instance... The Monarch?
Dr. Orpheus: If it would please the court.
The Monarch: Objection, no way!
Judge: This is most unorthodox.
Dr. Venture: Unorthodox! The defendant is in a crown for God's sake

Yes, little Rusty had a penchant for getting himself kidnapped about once a fortnight. I remember one time, I believe it was during "The Case of the Metal Mandingo"

Col. Gentleman

Careful, lad - his hands of those are strong enough to crush a boulder, but delicate enough to crush a butterfly

Col. Gentleman

Okay, this is getting weird! You're not going to tell me you went to college with the Monarch too? Where did you go to school - Super Crazy No-Way School?!

Hank

Hank: You see dead guys all the time.
Dean: When?
Hank: Dude, just last week Brock killed two dervishes with a pillowcase full of coats. Right in our bedroom!
Dean: He knocked them out!
Hank: Oh, sing yourself another lullaby, Baby Dean. The police took them away in body bags!
Dean: Sleeping bags! Those were sleeping bags!

Dr. Venture: Is my tie on straight?
Brock: Yeah. You can't miss with a clip-on.

Hank: It feels weird seeing someone else fly the X-1.
Col. Gentleman: Don't worry, boys. Despite Kano's racial handicap, he's an excellent pilot. Why, he can land this on a puffin... or a Smurf

Brock: This is you! You did this! I'm gonna kill you!
Underbheit: Brilliant deduction. You've discovered my brilliant plan to chain myself to an albino!

Oh come on! You're going to kill me because I had fake sex on graph paper with a girl who barely spoke to you in real life?!

Dr. Venture

The old fake coffin trick. Gadzooks, you think I would have remembered that one from "The Case of the Old Fake Coffin"

Action Man

Hank: So, how come you're not old and stuff like the others?
Otto: Oh, but I am. I'm half-Atlantean and so I age differently.
Dean: Wow. How do you get to be like that?
Action Man: A drunk sailor's gotta have his way with your mer-mom

Venture Bros. Quotes

Hank: You are not the boss of me
Sgt Hatred: Au contraire, I am tony danza to your spunky Alyssa Milano. I am full on Charles In Charge of you

Hank: Is it just me or does every Nazi want to clone Hitler? It's like the only they think about
Srgt. Hatred: It seems that way, right. I guess when everyone hates you, you just fixate on making rotten Hitlers
