Use a semi-thawed hot dog, which is easier to cut. With a knife, make a straight horizontal slit about 1" from the top. On both sides of the hot dog, make a slit upward so the hot dog looks like it has 2 arms. From the bottom of the hot dog, make a 1" slit upwards, to make 2 legs. Broil in the oven. As the frank cooks, the "arms" and "legs" will curl out a bit, making it look more like a person. When done, remove from oven and decorate with mustard and catsup.
