Finally came up with a few ideas

And, apologies for the few puns and stuff in advance... I don't know where they came from!
Corny Farmer
requires: farm with corn
A farmer comes to you with a problem. His father grew corn. He hates corn... The little skin part of the kernels gets stuck between his teeth, and... well, anyway. He'd really like to grow wheat instead. His wife bakes fantastically, and nothing beats the smell of home cooked bread!
-Wheat or corn, who cares? Let the man grow whatever he wants. (change corn on plot to wheat)
-What? Hot corn with butter and pepper is the a-maize-ing!? You'll grow corn, and you'll like it! (no change)
A "Miner" bit of Claustrophobia
requires: a hill with a mine
A recent rash of minor mining accidents seems to have caused a local miner to have a change of heart. He's tired of digging around in the dirt, and instead wants to work under the open skies... maybe with some animals... sheep, yeah, he wants to be a shepherd.
-Who wool-dn't want to get out of the mines? He's welcome to raise sheep. (change mine to sheep with pasture)
-Baaa. You don't want to work in the mines? I'll find someone to replace you. The mine stays. (no change)
"Ware" is this from?
requires: a civ on your continent that you haven't made contact with
A traveling merchant brings some exotic goods into the city that you have never seen before. You ask where he obtained the good, and he said from the nearby [civ].
-Inquire about the [civ]. (establishes contact with [civ])
-Ask the merchant more about the [civ], and pay him to make a map showing their location. (-15 gold. establishes contact with [civ]. Uses GOODY_MAP-type function to reveal a few plots in [civ]'s location)
-[civ]? Never heard of them. Huh. (no effect)
Kelp
requires: a coastal tile with no bonuses, Fishing (able to work coastal tiles)
A local fisherman has discovered strange sea plants that are not only edible, they're actually quite tasty.
-So my people have taken to eating seaweed? Whatever floats their boats. (+1 food in coastal tile)
Pagans? We don't need no stinking pagans!
requires: pagan temple
Several of the local folks have requested that the temple be formally dedicated to their god of choice.
-No. The temple shall stay undedicated, and available to all faiths. (no effect)
-Dedicate the temple to Mammon. (Pagan Temple loses culture bonus, adds +1 gold/turn)
-Dedicate the temple to Oghma. (Pagan Temple loses happiness bonus, adds +1 science/turn)
etc, I don't know the lore well enough... could be a quick-and-dirty way to easily add options for the other "missing" religions with minor substitutive effects here.
This Place is Hoppin'
requires: brewery
The local brewery is down to their last barrel of beer for the season! Naturally, a brawl breaks out over who gets it.
-Put the last barrel up for auction. Highest bid wins, but make sure I get my "special beer tax"! (+15 gold, -1 Happy in city for 10 turns)
-Here, have some of my personal stash. Drinks are on me! (-25 gold, brewery gains +1 Happy)
-Who gets it? I get it! It's good to be king! (5% chance of 1 turn revolt, but c'mon, you get the beer! Maybe have a RP tie-in like I mentioned in my above post)
Why are They Called Flood Plains?
requires: an improvement on a flood plain
Sir, some locals report that one of the area rivers have flooded, destroying the improvements in the flood plains.
-I hope they've got flood insurance. (lose improvement)
-Recoup the citizen's losses, and assist the poor people to rebuild. (-15 gold. This event will repeat often if you keep doing this, moron.)
-Build dikes to prevent this sort of problem in the future. (-35 gold. lose improvement. Change terrain from desert to grassland, remove flood plain feature)
-What? We're building where rivers obviously flood? Restrict building in the area and preserve the wetlands as a park. (no improvements allowed in that square, +1 Happy from "national parks" there)
Walkabout
requires: a worker, working
A group of serfs have stumbled across a cache of perfectly sized walking sticks while out working. They've taken it as an omen, and want to go on walkabout and see the world.
-They're nutters. Put them back to work. (no effect)
-Sure, why not? We could stand for some more exploration anyways. (delete worker, add 2 scouts)
Closer to Home
requires: a scout outside your culture
One of our scouts has just recieved a message from his family. His wife has had his first child! He'd really like to be transferred to someplace closer to home, and would be willing to take up arms in our defense to do so.
-Seems like a reasonable request. Make it so. (delete scout, add warrior in capital - maybe recoup xp from original scout, if possible)
-I'm sorry, but exploration is more important to us. He'll come home soon enough. (no effect)
The first step of the "Mason or Treason?" quest I suggested in the
Events, or Living World in particular thread could work as a 1-time common event, and is somewhat an example of what I mean by the RP event chain in my post above.
