01 - Fill a medium saucepan with water and bring to a boil. Add hot dogs and simmer for 5 to 7 minutes, or until thoroughly heated. Remove and allow to cool briefly.
02 - Use a small paring knife to slice a shallow rectangular section at one end of each hot dog, forming a flat surface for the fingernail.
03 - Make a few small, shallow horizontal cuts across the center and base of each hot dog to mimic natural finger joints.
04 - Secure a sliced almond onto the flattened end of each hot dog, pressing gently so it adheres and resembles a fingernail.
05 - Warm hot dog buns if desired. Place each prepared hot dog into a bun.
06 - Generously drizzle ketchup around the exposed end of each hot dog to resemble blood from a severed finger.
07 - Arrange on a serving platter and serve immediately for optimal visual effect.
