Okay, there's this group of 3 dwarves (Urist, Cog and Onul) heading for a fortress to trade, when their wagon breaks down and they have to drag it to the nearest hovel, where they plan to stay the night. suddenly, a mechanic pops up!
he says; "i'll fix that wagon, and you three go into my stockpile and pick out a souvenir."
needless to say, he was insane. as soon as the dwarves entered the stockpile room, he locked them inside. soon after, he coerced one of the dwarves to come back into his entryway alone.
he said; I'll fix your wagon only if you let me shove your new souvenir up your bunghole and you don't make a sound, not a grunt or even a laugh.
he shoved the -alunite mug- up the dwarf's bunghole, and the dwarf grunts. he is promptly shoved into the magma well.
after a while, he convinced the next dwarf to come back in.
he said; I'll fix your wagon only if you let me shove your new souvenir up your bunghole and you don't make a sound, not a grunt or even a laugh.
the dwarf hands the mechanic the plump helmet seed he had, and the dwarf laughs uncontrollably, and is shoved into the kitten pit and shredded.
Urist meets Cog down in the dwarven magma chamber of the afterlife, and Urist asks; why'd you laugh? it was only a seed!
Cog responds: I couldn't help it! I saw Onul carrying a statue towards the door!
