Bittercup Runneth Over

Bittercup Runneth Over is an unmarked quest in Fallout 3.

Walkthrough
Head into the Big Town common house and look for a pessimistic young woman named Bittercup. Then speak to her politely. When her extensive speech ends, reply that no one understands you either. Next, she proceeds to list every man she has dated in Big Town. After this, choose any of the first three responses. She will then want to start yet another relationship with you, at which point you may respond by telling her you're not currently in any sort of relationship. She modestly ends the conversation. If you return to her once every 24 hours, she will give you one of the following presents each time:
 * Squirrel on a stick
 * Purified water
 * Dirty water
 * Stimpak
 * Noodles
 * Blood pack
 * Nuka-Cola
 * Shotgun shells
 * 5mm rounds
 * 5.56mm rounds
 * 10mm rounds
 * .44 magnum rounds
 * .308 rounds
 * Caps

Behind the scenes
The name of this quest is a play on the phrase "My cup runneth over", from Psalm 23:5 of the Bible, "Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over."
