Get a deck of blank faced cards. Write "Do the Chicken Dance" on one card and "Kiss Me" on another. Select two beautiful spectators.
Begin the effect by telling the spectator that you have written down different instructions on the card and each spectator has to do what is written on the card. Ask each of them if they agree to do whatever is on the back of the card.
Force the "Do the Chicken Dance" card on the first spectator. Before they look, remind them that they promised to do whatever was on the card. They will probably do a bad version of the Chicken Dance.
Then force the "Kiss Me" card on the second spectator. Before they look remind them that they agreed to do whatever is on the card. When they turn over the card, say "that is unfortunate, but you have do what is on the card." Chances are they will kiss you (on the cheek, the lips, wherever).
If they ask why it is unfortunate before they kiss you, tell them "you have to do what is on the card first and then I'll explain." If they ask after they kiss you then you give the explanation. If they don't ask, then (after the kiss) say "remember I said this is unfortunate, do you want to know why?" They of course will say "yes."
You then explain why it is unfortunate by showing them that every other card in the rest of the deck says "Strip Naked." Chances are they will smack you and have a good laugh. However, they may just smack you. I'm not responsible if they smack you really hard or knee you somewhere you don't want to be kneed.
IMPORTANT: This is not an effect to use a classic force for unless you are 100% accurate. You could get smacked (or kneed) without getting a kiss.
WARNING: Don't practice this effect on your mom or dad.
