Cut hardboiled eggs in half lengthwise. Remove the yolks and make filling
for deviled eggs. Cut out a small hole from bottom center of each egg (about
5/8-inch diameter.) Poke a black olive partway through each hole and hold in
place by filling eggs with yolk filling.
Place each egg, olive side up, on a Ritz cracker. Paint red lines, resembling
blood veins, with a toothpick on the eye.
