p>Most people are familiar with this one. Find the red card amidst two black ones and win whatever amount you bet. While you watch, someone does just that, and then persuades you to try your hand. You never win since the hustler is palming the cards. The "winner" was a plant. Even if you win, pickpockets will relieve you of your cash. Or right after you place your bet, someone yells police and the operator disappears with your money.
