You know, it probably would be faster to say "the entire series" and go to lunch earlier, but I guess we're all committed to this. And there is Episode 5.note (That is, the real Episode 5, not "Fanfic Mode.")
In Episode 2 - The way Luffy says "Ah yes, swords. Nature's knives." It just made this troper burst out in laughter at the absurdity of that statement.
Episode 3 - Shank sitting with his hand in the air, and suddenly, without it being commented on, a waffle simply materializes from his hand.
"I WON'T GO BACK TO PRISON, MY BUTTHOLE CAN'T TAKE THAT ABUSE!"
"If there's something you need to know about me, everything is made of rubber. And before you ask, yes. Yes, it is." What made it especially funny for this troper was that he was going to ask that exact same question until Luffy answered it in anticipation.
Also funny because the creator of the actual One Piece was once asked that as well, and he also answered in the affirmative, going so far as to have it be pointed out in the story itself.
"Sorry I punched you in the face and broke your daddy's statue! Think we can still be friends?"
Luffy's variation of a childhood insult had this troper in stitches.
I am rubber and you are fat! Don't you dare touch my hat! *Megaton Punch*
In episode four, Zoro gets finished lugging Luffy in a cage. Then Nami brings a key a Zoro yells about Nami having the F***-ing key. The hilarious part is that the next Sound Effect Bleep manages the fail to cover up the F-bomb, being placed right before it.
I DRAGGED HIS ASS TWO MILES, AND YOU HAD THE *BEEP* KEY THE WHOLE *BEEP* FUCKING TIME!?
Morgan: That's it, you pirate bastards! You're all going to die! I'm going to chop you limb from limb! You're going to have a little bit of the captain in you! You will die so badly you will be dead and then you will stay dead and - he's not listening, is he?
"Son. I look like a Bond villain and there's some guy running around who sounds like Sean Connery. SHIT IS ABOUT TO GO DOWN!
Episode 14.5/5 may qualify for being one of the funniest videos in the history of the internet. PURE CRACK doesn´t even begin to describing it.
Particular parts to note: the cameo with the two Code Ment soldiers fighting over cheese, Death the Kid chasing down Lelouch and the entire party sequence (Lelouch is terrible a beer pong).
Zoro: "I'd suck a fart out of her ass."
Also worthy of note is Luffy's way of getting into Miss Kaya's estate.
Zoro: "Why don't we just try the front door like Nami and Usopp?"
Luffy: "Because my idea's better. *zoom out, he's strapped to a rocket* NOW LIGHT THIS BITCH!!!"
And so the partying commenced:
C.C: "You know what would be great right now?"
Zoro: "Eating licorice?"
Luffy: "PUNCHING A SWINGSET!"
Suzaku: "eating licorice!"
Lelouch: "RIDING A HOVERBOARD!"
Suzaku: "EATING LICORICE WHILE ON THE HOVERBOARD!"
The long rant where Kuro rages about how he was a butler for three years.
Kuro: (to Django) "Well it may not be a big deal to you; but outside your contact, the only people I've been able to hang out with are some weird annoying girl and a goddamned lamb-man! Let me repeat that: a god damned lamb-man! He's a ***ing man and a lamb. I have nothing in common with a person like that! What could I possibly talk to him about? "Oh yeah, how much do you sell your wool for in the market, I got jack shit because my dad didn't *** a sheep!"
Django: "Ya don't have to be an asshole."
Zoro: "Yeah! Whoo!" Usopp: "What the hell's going on?" Luffy: "Zoro's drinking beer." Zoro: "I'm drinking beer!" Usopp: "I... thought we were going to fight some pirates." Zoro: "Fuck, I'm drunk!" Luffy: "Zoro's just getting ready in his own way." Zoro: "Ah, shit, I spilled it!" Nami: *looks at Zoro* Zoro: *covered in beer* "What are you looking at?" *Nami holds up a match* "Please no!" *she tosses it, Sufjan Stevens' "Chicago" plays as we hear Zoro screaming. Zoro eventually runs off, still on fire* Luffy: "Take a good look: there goes a champion. You know, you'd think these pirates would've shown up by now." Usopp: "Well, they could be at the other port." Nami: "There's another port?" Usopp: "Yeah, there's another port on the other side of the island." Luffy: "You are just comprised of fail, aren't you?" Usopp: "Failure breeds success." Luffy: "Then somebody'd better man up and give the sexification to Khloe Kardashian. Ha ha ha! Onward! To battle!" Usopp: "Wait! What the f**k does sexification mean?." Nami: *facepalming* "Just look on the bright side, how could this get stupider than it already is?" Zoro:"Hey, you kids wanna be on fire?" Caption Text:"I think we can go stupider... let's check on Luffy." Luffy: "Damn it man, I'm a pirate, not a doctor." (a glowing rock face makes strange noises) Luffy: "Because I don't know about space-time travel." (cut back to glowing rock face) Luffy: "That's bullshit." (rock face is making higher-pitched noises) Luffy: "That's it, you're goin' down." (jumps at rock face and vanishes)
Then Django arrives:
Usopp: "Those must be the pirates." Nami: *panting* "Ha... I'm here. Where's Luffy and Zoro?" Django: "Hey, you there! What are you doing?" Usopp: "Oh, shit! They've spotted us!" Nami: "Shit, what's the plan?" Usopp: "We need to stall them. I got this. Well, well, well! If it isn't the bloody pirates." *Intro to awesome music begins* "I couldn't help but notice you cowering in fear of me! Continue to do this, as this is the proper action when faced with the great and powerful Usopp!" Django: *music stops* *[to his men]* "Who is this clown?" Pirate: "I think he's like a lunch monitor?" Usopp: *music goes into crescendo, increasing in epicness as it does* "Your deliverance will soon be at hand, my friends! Killing you will be frosting on my murder-cake! This day is" *farting sound* your reckoning! Should you want to live, you best kill yourselves now!" Django: *sniffing* "I'm sorry," *music stops* "but... did you just poop?" Usopp: "Alright, let me check." *shitting sound* "Uh, yes, yes I did." Django: "Oh... God..." Usopp: "I'm sorry, I thought I was ripping ass." Beat Django: "Alright, enough of this." Nami: *whispering* "Ok, what's plan 'B'?" Usopp: "Nami, my nose is six inches long, I'm wearing a hair-net, and I just shit myself. Do you really think I have a plan 'B'?" Django: "Hey, can you and Misty get out of our way? We're... kind of in a hurry here." Usopp: "If you plan on attacking these villagers, you'll have to do it on my grave." Django: "Villagers? What are you talking about?" Usopp: "Don't play fucking dumb!! Me and Luffy heard you pirates talking about the attack on the villagers!" Django: "What are you talking about? We're here to attack the cat problem." Usopp: "Ok... I'm completely lost." Django: "We're here to spay and/or neuter the cats on this island." Usopp: "Eugh." Django: "No! Don't, 'eugh'! It's good for them; they live healthier lives."
Then Zoro arrives:
Zoro: *panting slightly* "Ha... There you guys are!" Django: "Great, they're multiplying." Zoro: *panting* "Alright... What'd I miss?" Usopp: "Apparently, they're just here to spay cats." Zoro: "What, for real? That's kinda weird. What, do they, like, go from island to island, spaying cats?" Nami: "Yeah, pretty much." Zoro: "Ugh, I don't like it." Django: "It's good for them!" Usopp: *whispering* "I don't know, what if they're lying? We should still protect the villagers." Zoro: *whispering* "Ah, don't worry, I already took care of that." * Cut to the entire village on fire and screaming in agony. Cut back to Zoro.* beat Zoro: *whispering* "They can't get touched if they're on fire." Django: "Ok, I can't take it. Mr. Whiskers! Mr. Tinkles! Attack them!"
