Get Chip's spleen

Get Chip's spleen is a side quest in Fallout 2.

Detailed walkthrough
You can find Chip standing south-east of the General Store on the tanker. Speak to him, and you'll find out that he lost his spleen in a bet against Lao Chou.

Find Chip's spleen
Speak to Lao Chou, at the Flying Dragon 8 general store, and he'll inform you that he gave the spleen away to Dr. Wong Yi Tze. He had no use for a spleen, after all.

Ask Dr. Wong about Chip's spleen. He intends to eat it with fava beans and a light chianti. Tell him that the spleen is human (you get one option to do so). You'll receive 2000 XP.

Transplatation
Go back to Chip, then he will want you to ask Dr. Fung out in Chinatown to put his spleen back in for him. Talk to Dr. Fung, and ask him to put it back. You'll need to pay $1000 for Chip to get the surgery. If you've spoken to Doc Holliday in Broken Hills about his friendship and mentorship with Fung, and mentioned it to Fung before, he'll put the spleen back for free.

Talk to Chip again - he'll tell you to wait for a day, then get back to him. Afterwards, he'll leave the tanker.

Visit the same place again, Chip will be there (with his spleen intact) and you'll get another 3000 XP.

Rewards

 * 5000 XP.

Behind the scenes
The whole spleen dialogue with Dr. Wong is a reference to The Silence of the Lambs.

Bugs
Occasionally, if you speak to Chip as he is walking away to have his spleen restored, he will never return to the Tanker, and never reappear anywhere else, however the quest will remain active in your pipboy.
