One of my faves is having disaster strike some unsuspecting people, and the players get the choice of chasing down the source of it or saving the people. Burning inns are great for this sort of thing.
Captives create a lot of issues, too. Bashing down doors alerts badguys, and I'm willing to execute NPCs if it means getting the players to be more stealthy at times.
Another is the cursed item: give them a magic item that is da shizzle. Then make it intelligent, and horribly, horribly evil. But make it act like their buddy. "My precognition tells me the king's steward is going to poison the king and rape the queen! You must stop him!" Of course, the steward is a Lawful Good alchemist, so he's not going to do that, but the alchemy part of the equation makes it believable...
Finally, there's the inter-party sacrifice: give one player a prophecy that seems to say something to the effect of "If you spill the blood of a good, holy soul at the Temple of Orcus, you will break the undead god's power over the temple." When they get there, the only holy character is the Paladin in the group. Does the player attack the Paladin? Does he tell him the prophecy? Is the prophecy even true? Do they have to wait for some other holy dude to come along?
