Context: We’re playing a halloween oneshot campaign for paranoia with premade characters. One of them has the secret goal to stab as many people as possible with a certain knife that would summon eldritch horrors by drawing a card. He has just done so.
DM: All right… let’s see here… *draws a card and starts snickering*
Everyone: What is it?
DM:They’re really scraping the bottom of the eldritch horror here… You just summoned A Literal Roomba.
*Laughter from table*
DM: The strange device turns on and begins to suck up the dirt floor, digging itself into a hole in the process. After a few minutes of this a light turns on and it says “Filter change needed.”
