Mine has to be the Russell Crowe episode. It has the most quotable lines of any episode in the series, in my opinion. He belts gems such as:
-"Oh my god, it's Russell Crowe! Oh My god, it's bleh bleh bleh! Why don'tcha flush yourself down a toilet, ya cunt!"
- "Croikey, it's a choi-nese man! Summa these people can grow t' be foive foot tall!"
- "Ah'll foit yeh, yeh testicle!"
- "Ah'll punch yeh in the vagoinah!"
- "Makin' mewvies, makin' songs an' foitin' round th' wooooorld!"
- And the end theme, "Tuggah's 'orn's a blowin', it's toim t' be a goin', no more Russell Crowe'n for yeeew"
My second favorite is the one where they get the Chinese guy from the City Wok to build a wall.
-"Gawd damn mongorrians! Stop tearing down my sheety wall!"
-"Goddammit, how come every time us chinese put up a wall, stupid mongorrians have to knock it down?"
The City Wok guy is my favorite character.
-"Mr. Twang Liu Kim: hahaha! mah master plan! when mongowians come to destroy the shitty wall, i'll pour this sweet and sour pork on their heads! oh, sweet and sour pork so hot and-a sticky, mongowians'll stick right-a to da wall and scream awooooooo!" "oh, i get it. a trojan mongowian howrse. mongowians hidin inside thinkin i'll bring it in the shitty wall, then mongowians pop out and destroy wall from da inside out. okay. i'll pray arong. oh! oh rook! my very own mongowian trojan horse! row! reah, what a great present! i guess mongowians aren't such crappy, smelly people after all, yeah! i'm just gonna bring it inside and show it to all my friends, yeah. (opens hatch, sweet and sour pork falls on him) AWWWW! (smacks lips) AWWW, ITS SWEET AND SOUR PORK!
(Mongolians laughing, swords clanking)
(as sweet and sour pork hardens)
im gonna get you nongoldians id ids da lasd ding i dooooooo!!!!!!!!!"
The nastiest ones were the blood orgy and when Kyle's knees explode.
