PØNZI - 2 Envelope Bank Night

Two envelopes are introduced. One contains a cash prize and the other contains a useless piece of paper. The participant is given a free choice of either envelope. If they choose the envelope with the money, they keep it. No matter which they choose, they will always wish they'd chosen the other one.
