I found this game on gendou.com
The mechanics:
I will post the first wish, then the second poster will corrupt my wish and then tell his/her wish too. The following poster will corrupt the previous wish and so on...

Example:

A : I wish i am a super genius.
B : You're a super genius but due to it your head exploded and you died suddenly. I wish i....
C : You are... I wish...

The usual rule: you can corrupt someone else's wish again only after 4 posts.

I'll start.

I wish i can fly...

you flew ...straight into a jet turbine(hehe)i wish that had two twinkies right now...

You choke on your two twinkies.
I wish I had all the manga and anime I wanted.
