This thread chronicles the adventures of SpiralDimentia and forum members managing to trick him into removing the cotton candy sword from a curious structure and experiencing spoilers. To his credit he took it with a great sense of humor and it turned into an epic thread of awesomeness.
SpiralDimentia: Oh god, you guys are dicks, I think I just unleashed a horde of demons into my base.
At one point during the thoroughly insane succession fortress Battle Failed, a forest titan wandered onto the map. The militia prepared to defend the fortress from the monstrosity... and then this happened.
Engravers, who tend to troll other dwarves (mostly the ones in a position of power) by covering every fifth tile they engrave with an image of the current position of power, surrounded by their most hated vermin (worms, bats, toads, insects, etc) and cowering. Not only are they engraving the fort with political satire, but the mental image is hilarious.
Quite a bit of the engraved material is worthy of a good chuckle.
As polished as the game is, sometimes the grammar is a bit off. Case in point? "His guts is broken."

And the hilarious "Floating Guts guts".
This thread about a Bronze Colossus that was chasing after a kitten:
"The Bronze Colossus punches The Stray Kitten in the head with its right hand, but the attack glances away!" Poster: It tried punching it in the head at least 12 or 13 times, but every time the attack glanced off. What the hell was that cat's head made out of, slade?
They have the [MOUNT_EXOTIC] tag. Draw your own conclusions.
Without a nervous system...
The only thing they can feel...
Due to copious amounts of Noodle Incidents and unfortunate selection of topics and titles, the procedurally generated books can be quite funny. Some examples include vitriolic rants against a random town the necro never visited, and books about books about books about themselves, give or take a few layers.
A Note to Urist - wherein fortress Overseers express their frustration with their epically stupid dwarves.
On the Adventure Mode page on the wiki, one of the FAQ's is, "I managed to escape but all my limbs are gone. Now what?" It then goes on to talk about what you can do, depending on what limbs you are missing. If you have all your arms and legs gone, it talks about how you could wrestle people to the ground and kill them using only your teeth.
DF Talk #19: Rainseeker, Capntastic and Toady One discuss ways to discourage nonsensical training methods like having the credit your adventurer gets for slaying a troll diminish as villagers come to see him as the dumbass who throws rocks and wrestlers badgers all day.
