Gator Fishin by Timco Magic (watch video).
A mini deck (supplied), is shown and shuffled, a card is selected and returned to the deck. While the spectator mixes the cards, the performer brings out a small paper bag, claiming he has a pet gator inside. He also claims the gator can do a card trick. He reaches inside the bag and slowly lifts out a chain, on the end of which is a gator catcher. The mixed deck is dribbled into the bag, then the gator catcher is lowered. After only a second or two of sniffing, the gator catcher is raised out of the bag with the selected card in it's mouth!
