I once took someone's nose with my hand. They were really impressed until they realized it was just my thumb.
I used to do a pretty good card force trick where I would look at the bottom card of the deck, and then I would tell them to point to that card, but not look at it, then I would look at the card, and tell them to pick that card, and then do it again. Then I would say I would pick the next card, and pick the bottom card. Then I would lay down all 4 cards and say "You pick this, this, and this, and I picked this", and the other person is just like wut.
Me: Take this card.
Victim: Okay. *takes*
Me: May I see that?
Victim: Sure *gives*
Me: Is this your card?
They somehow see through it though! :/
This next trick really only works if you've done a trick already, so that they just kinda go along for the ride. You tell them to pick a card, any card, and fan out the cards in front of you, but you fan them so you see the face of them. A lot of times, people won't catch it, and then you laugh at them mercilessly
