Today's Contestant
You're in class, at work, etc. Suddenly, your phone rings. You pick it up, and a voice on the other end tells you that you're the surprise contestant in a game show. The voice, which sounds familiar because it belongs to your partner, assures you that if you answer the surprise question correctly, you'll win an unforgettable night that ends with an hour of the most intense pleasure imaginable. If you get the question wrong, you agree to some sort of penalty, like becoming a 'slave' for a few hours...
Wouldn't it be nice if this scenario happened to you someday? I'm sure your partner would love it too :) Think of a question or challenge that could be stimulating enough before 'inviting' someone to participate in your game show. Be mindful of the difficulty of the question; it shouldn't be too easy (that would ruin the fun) or too hard (it's not about causing frustration). Give some time so that at least an attempt can be made to find the answer.
Don't limit yourself to just one edition of your game show. Like any successful program, it can be reissued from time to time with new questions and stimuli ;)
Finally, for those who feel a bit shy about proposing such a situation over the phone, remember that some game shows don't hesitate to use letters, emails, and texts when it comes to testing their participants.
