How did he do it??!! Zat iz ze question...

Luffy:"Okay Zoro, now YOU lean back so that I can get some floor food."

Zoro: I can haz cheezburgerz!

And to think this all started with an argument about a Jello pudding cup...

OK, another one:

The real question is not how did he manage to get the sword in his mouth, but how will he cut through those IRON CHAINS with it...

Where is One Piece? And there is no shame in being left handed.

Luffy: Zoooooorrrroooo your swords are digging into my back.
Zoro: -sighs- well theres really nothing I can do since you got us tied together with this damned chain.
Luffy: aw but zoro you know you love it....but searously get your swords out of my back.
zoro: -growls- if I could move my arms I would take this sword out of my mouth and cut your neck open.

Luffy- "Yo ho, yo ho, a pirates life for me..."
Zolo- "If you sing that song one more time there will be no pirates life for you!"

Luffy: Hey Zoro! You were right! This is better than six flags!!
Zoro: -_-

And thus 4Kids set the pirates adrift, sentenced to fates and fan-fictions unknown...

I've got two...

Day 4

--------or-------

Zolo: I'm starving!
Captors: Here!
Zolo: -_-*

Zolo: If someone puts up one more silly caption of why I'm tied up, my sword is in my mouth, and Luffy is behind me, I swear...

Oh, I got another one...
Luffy: ...and this is how it goes: I know a song that gets on everybody's nerves, everybody's nerves, yes, on everybody's nerves...
Zoro (Thinking): Urge to kill, rising...

Zolo: "I see a wave of enemy troops!"
Luffy: "I see melons."

As a child, Zoro's mother would always tell him, "Take that thing out of your mouth this instant!" He never listened.

This situation would have been a lot worse if not for the spirit of MacGyver in the sword.

well, at the very least, you can't say i didn't have your back...

Luffy: Look out Zoro! There are millions of fangirls taking screen-caps of this scene!
Zoro: THE FIENDS!!!

---or---

It's not what it looks like! (It's even better! ^_~)

[or]
Zoro:"I can take you all on, even with both arms and an idiot tied behind my back."
Luffy:"Same here."

Luffy:"I can't understand a word your saying, there's no subtitles on my side."

Luffy: That was some weekend.
Zoro: You got to admit, it was worth it.

Luffy:Ok man, get us outta here!
Zoro: Not until I figure out how that dude in the marketplace ate those swords!

These are the moments when Zoro wished he could turn his head a full 360 without being possessed.

This just raises more questions than it answers...

Or~

Luffy: Whoa, this is exactly what I expected when you said you were "Armed to the teeth"!!!

Yoji.

Even in the face of death, Zolo is determined to learn how to fence without the use of arms.

zolo- Dam I have to hang out with Luffy, and I am out of tooth picks

Houdini was famous for swallowing and regurgitating keys and lock picks to use in his death-defying escapes. That said... Houdini's got nothing on this guy.

Luffy: I thought you said we were going to visit a Queen
Zolo: He is a Queen, and in more ways then one

Are you having a hard time figuring out how did he manage to unsheathe that sword? Try imagining where it was hidden...

Luffy:you had to try THIS trick now did ya?
Zolo:shud up... >:C

Sorry I fail XD

Either his captors are really stupid, or his neck is incredibly flexible.
