The Tiger Trap was a rigged and baited rope intended to lure and restrain tigers. It was featured in the very first Calvin and Hobbes strip; in it, Calvin revealed to his father that he had rigged a "tiger trap", baited with a tuna fish sandwich, the previous day. The trap was a success, as it caught Hobbes without apparently harming him. Tiger's do anything for a tuna fish sandwich, as stated by Calvin.
