Method:
Start the trick by presenting three Jacks and make up a story about them being three best buddies and how they couldn't stand being apart.

Continue to rant on on how one day the three amigos were lost in the desert and the best way to seek help was to go in different directions. The first one to get help was to come and get the others, so off they went in their different directions.

Get the spectator to place one Jack on top of the pack, one Jack anywhere in the middle and the last Jack on the bottom of the pack.

Confirm with the spectator that he is happy that the Jacks are well separated, then get him to cut the pack ensuring that the bottom half of the pack is put on top of the other half.

(This will bring the top and bottom Jack together with the previously placed Jack)

The cards are then turned face up from the top off the pack eventually turning over three Jacks together near the center to the spectators amazement.
