The set-up's important
So, our party gets to a village that’s oddly run by goblins, but that doesn’t matter much in the moment, and we go about our business. Well, at some point, we’re asked to clean the manure out of a pig pen and, my monk having just learned water whip, decided to assist our goody two shoes cleric with cleaning it out by getting it all in one sweep. For some odd reason, though, the DM decided to actually roll a save for the manure. It got a nat 20, and so this exchange happens.
DM: as your whip goes to sweep away the pig manure, something strange happens and, suddenly, the manure swirls around and shapes itself into a roughly human form. Roll initiatives.
Monk (me): you can NOT be serious…
DM: oh, I am.
Monk (me): are you shitting m-oh goddamnit!
The bard lost it at the pun and the cleric proceeded to politely ask them to become field workers without a fight.
