During the final session of my campaign, my main NPC was giving his huge speach, revealing how he was about to summon a massive demon.
NPC: …“and you will all now witness as I bring back the demon known as…..”
His speach was interrupted when one of my players let out a loud and squeaky fart at the table
NPC: “That’s funny, I didn’t realize these dungeon floors creaked”
The group broke out laughing.
Later, during the battle, the demon himself was speaking
Demon NPC: “You puny creatures will all fall under my control as I….”
His speach was also interrupted by another loud and squeaky fart
Demon PC: “Huh, I never knew that stone floors creaked”
