Preheat oven to 400°F (204°C). Line a baking sheet with parchment paper.
Cut French bread in half lengthwise, then slice each half into 2-inch pieces. Arrange bread slices on the baking sheet.
In a small bowl, combine butter, parsley, Worcestershire, garlic, and salt.
Spread garlic butter over each slice of bread.
Bake for 5 minutes, or until slightly golden brown.
Remove the bread from the oven and peel the string cheese into thin strips. Wrap the string cheese around the garlic bread to create a mummy-like appearance.
Place two black olive halves on top of the string cheese for eyes. (If using candy eyes, press them on at the end.)
Return the baking sheet to the oven and bake for an additional 5-7 minutes, or until the cheese is melted and bubbly. Serve immediately.
