This is fantastic dialogue

And is totally how you get hardcore munchkins to roleplay

Okay, so you want to build a badass? Don't just tell me, show me.

Well it won't talk, so it will not tell joke but it know to apreciate a good one when it ear it.
it is said that this sword have a very sharp sense of humor.

If you want knock knock jokes, you should get a hammer.

Get an intelligent spear for some piercing questions.

Don't debate with an intelligent dagger, though, it cuts to the heart of your arguments.

The last one I met was just a backstabber though...

You can go for a bat, it make some striking observations.

The talk about the sword having emotions - and Luke constantly wondering if the sword talks - reminds me of my very first D&D experience that actually involved a table and dice and all that.
I wasn't really clear on the rules and all that, so making my own character was a bit beyond me...but the player who brought me to the table had just gotten a magic, talking sword. So he convinced the DM to let me participate by roleplaying the sword.
The DM gave me a bit of character direction. "Sassy. Scottish. Bloodthirsty. Otherwise,go nuts."
...and go nuts I did. I got full on into the character of the sword, and at some points combat - even the campaign as a whole - had to be put on hold while players (or even DM) struggled to get their breath after laughing too hard. To give me more sense of participation, the player whose sword I was convinced the DM to add a new slightly meta mechanic. If we were in combat and dialogue directed at the enemy made the DM laugh aloud, he and I would each roll a D20. If I rolled a higher roll, the enemy would be briefly 'stunned' from paroxysms of laughter. If I rolled a 20 (since no stats involved, considered a nat20), the enemy would 'die laughing'.
...I had the highest kill count that session. Pity I never got to go back to that table.

That is both amazing for a newbie and a great story.
i love the the table top rpg community.

That's a nice way to bring someone in. and it make for one very fun session.

I love that scene, but I do remember it being poorly animated, with one frame having the sword pass in front of Zoro that would be impossible for the way it was falling.

I'm now imagining someone saying "Be glad this sword doesn't talk; remember the Excalibur from that one game?"
