"Don't worry, it's on the King"
The wallets have a message (posted above) and could have anywhere from $1-1000 in them - straight up cash.
I like this idea but wonder how heavily BK will be pursuing it in the mass media (and how many wallets they are thinking about actually dropping). I also wonder if they've targeted popular people (celebs, etc) to talk about the experience and film them for web use (like any reality TV "surprise your on camera" show).
