Ahh yes, my current idea:

Create stickers, small circles ~approx. 2 inches in diameter, and printed on them will be something to the effect of:



Once printed up, every fast food store in my vicinity (McDonalds, Jack-In-The-Box, Burger King, Two Subways, KFC) will somehow, magically, only have "Toribash" available from the soft drink dispensers.

Fairly harmless, yet effective. The hardest part will be taking a picture of it. . .
