Gently place eggs in a single layer in a saucepan.

Cover with cold water, ensuring eggs are covered by about an inch.

Stir in 1 teaspoon of white vinegar.

Bring the water to a rolling boil over medium-high heat.

Once boiling, immediately turn off the heat, cover the pot, and let the eggs sit for 12-14 minutes.

Immediately transfer the eggs to an ice bath for at least 5 minutes.

Gently tap each egg on a hard surface to crack the shell, then peel under cool running water.

Cut each egg in half lengthwise.

Carefully scoop out the yolks and place them in a medium bowl.

Use a fork or potato masher to thoroughly mash the yolks until they are smooth and creamy.

Add the mayonnaise and Dijon mustard to the mashed yolks.

Season with salt and pepper to taste.

Mix all the ingredients together until smooth and creamy. Taste and adjust seasonings as needed.

Choose your filling method: Spoon the yolk mixture back into the egg white halves, pipe the filling using a piping bag fitted with a star tip, or use a Ziploc bag with a corner cut off.

Decorate as Spider Eggs: Cut a black olive in half lengthwise. Place one half on top of the deviled egg filling to represent the spider's body. Slice the remaining olive half into thin strips to create the spider's legs. Arrange the legs around the spider's body.

Decorate as Ghostly Eggs: Arrange a few strands of chives on top of the deviled egg filling to resemble ghostly hair. Lightly dust the edges with paprika to give a 'spooky' effect.

Decorate as Bloody Eyeball Eggs: Using a toothpick, carefully dab a tiny amount of sriracha or hot sauce in the center of the filling to create a 'bloodshot' eye effect.

Decorate as Graveyard Eggs: Sprinkle a thin layer of Everything Bagel Seasoning around the base of the deviled egg to look like 'dirt'. Use short pieces of chives to resemble stems coming out of the graveyard.

Arrange your spooky deviled eggs on a platter.
