Players are hams. Give them a soap box and they'll make a speech every time, as long as their character is involved.

Tell a Story about a time one of your players appealed to a crowd with a speech, whether it worked or not.

One player was playing multiple characters in a sci-fi campaign. The characters were separated at the time, both trying to bring down an evil organization dedicated to using time travel to control the universe.

They both gave epic speeches to a crowd, trying to convince them to rise up against this organization and band together to bring them down.

One of said characters was being held prisoner by the organization at the time, and giving the speech to its members.

It worked quite well for the player outside the group. They brought in an army of monstrous humanoids to keep reinforcements away by going after the organization's bases. The one inside the group... not so much. Several of the villains just plain walked out on it, and then a dragon tried to devour the character's face, at which point the crowd quite sensibly changed their focus.

(I'm french, so ming my typos.)

I love classes with a lot of charisma to make such speechs.

One day during a campaign, we were back from a misson with my group, and the female ogre player in our group missed critically his intel roll, making him think that a noble followed by guards for protection needed a change of diaper. (That's how silly our DM was.)
So the noble got stripped of his clothes and the ogre used the noble's top to wrap it around his legs like a diaper.

As he was done with his work, the noble obviously screamed at his guard to murder this foul beast. Half of my collegues around the tables talked out of characters and said that he was doomed, already resting their case about him, speaking about running away, but i was not having it.

I steped between the advancing guards and the ogre and i yelled the biggest lie of my carrer :
"I OBJECT ! How dare you inrreupt the sacred ritual of mother ogre the third ?"
I then lectured them for more than 5 minutes, spewing lies after lies, inventing a lore on the spot about how, when a lady ogre does a diaper change to a human, it was one of the greatest honor and proof of friendship and compassion for another race.

I also warned them :"And don't you dare stop her, have you heard about the town of *random name i made on the spot alongside the story*, of course you haven't, a swarm of angry raging ogres crushing a town to thin dust makes it harder for the history books to keep records ! Tell me your name noble ! For when i run away from here, and you stop that ogre, i may tell the historians the name of the man who caused the destruction of this town !"

The table went silent around me, and the DM suddently went :"... I'm not even making you roll this one. The noble and his guards slowly steps back away from the ogre with a new scared eye on her.
They appologize and walk away."

The ogre player thanked me profusely, for i saved his character from certain doom.

I believe that is the greatest story I have ever heard

You know there's techincally already a system for this kind of thing in-game.

It's called a bard, and essentially what's happening here is that the crowd is acting as one big one.

...Oh, I thought that was the crowd getting those bonuses. :| Figured they'd probably need them more than the party.

Basically, yeah, but there's technically not a rule for morale support by crowd's, not that I'm aware of at least, but I seem to recall various monsters and the like getting buffs like this on occasion. So, three cheers for the mob bard err bardic mob? Whatever. Luffy kick Arlong's keister!

actually there is

I love it that pathfinder has rules for this.

Wait, is this the moment they get the name, or have I forgotten when they started calling themselves that?

If I recall correctly, which is a long shot, the Navy called them that because it's the most idiosyncratic feature of their flag.

I think peoples just call a crew by it's captain name or the symbol they use in their jolly roger. sometime by their ship

Luffy is Straw-hat luffy, His emblem his a skull with a Straw-hat, that make his crew the straw-hat pirate.
