Well, how i can start...
[Inspired on CipherSaber]
I wanna disguise arcfour as a game (board or virtual), give it for free to kids, and someday tell them the goverment has banned the game because it's basically undistingable from arcfour, and then i'll try to explain for them the crypto controversy, and i know i did my work well if at least one of them decides to write a letter to the goverment.

I mean, i clearly know this is so frigged up, but i wanna know if it could actually work.
