Field day? No kidding.
Genasi Monk: "Let's teach the Kobolds the principles of micro- and macroeconomics."
There's a wonderful blog: http://outofcontextdnd.tumblr.com, to which people can submit all sorts of weird and wonderful quotes from various roleplaying games. These are some of the favorites that I can remember:
DM: "Okay, the next person to make a pun loses 50 xp"
Player: "I would like to talk to the water nixies."
DM: "What about?"
Player: "Current events."
DM: "You hear that all too familiar song, and immediately recognize the war song of the orcs. The last notes of Wonderwall play before the horde advances."
PC with thick Russian accent: “Hello! I hear you sell rat poison. I have rat problem. Do you have poison for 6 foot tall, 180 pound rat?”
Racist Taldor Cavalier explaining ‘Elven Ancestry’ to the party’s Elf: “Well, look at it this way: Elves and squirrels share three distinct traits. One: both creatures traditionally live in heavily forested areas up in trees, two: both subsist largely on a diet of nuts and berries, and three: worst of all, both have pointed ears.”
DM: "The Barbarian begins eating the summoning circle."
Story time: "The patrons are looking towards us and the bartender asks: "why did you bring weapons in here?" We replied: "Mimics." We laughed, they laughed, and the table laughed. We killed the table. Good times."
The Rogue to the Fighter: “Maybe you should use your +8 to athletics for something other than jumping to conclusions”
DM to the party fighting a giant snake: "It's already prone, guys!"
At the end of a Feudal Japan themed campaign: "My velociraptor goes off to found its own kingdom."
Underdark politics: “It says a lot that, of all the groups in this dungeon, I think the Satan-worshipping orcs are the most trustworthy.”
Necromancer: "I need minions. Do you see any corpses?"
Necromancer: "Can you make some?"
DM after the Half-Orc suggested using a town's indoor plumbing for vodka distribution: "The Dwarves, in the drunkest of stupors, elect you their queen and erect a statue of you pouring alcohol into the Town Square toilet."
Concerning the Warlock's pet: "Did you bring the eternally screaming goat?"
Party character recap: “So we have a memory wiped Anubis, Thor with a hammer that causes sex changes and turns things into beavers, a powerless Eldritch abomination, the Doctor whom hears all of our voices, and a chef who may or may not be Superman.”
Gnewton, Gnoll physicist: “Every Standard Action has an equal and opposite Free Action.”
Fighter logic: "Well, a wise man once told me that your greatest enemy is yourself. I knocked myself out by walking into a tree once, which means I have already defeated my greatest enemy. That Dragon should be a piece of cake by comparison."
Bard with plans: “Okay, a 43 to disguise myself as a raven, a 39 on Stealth to sneak up on them, and a 42 on Bluff to convince me to accept them as one of their own.”
