place ketchup in the serving bowl.

cut each hot dog in half

using your pairing knife and the uncut end.. cut out a small piece of the hotdog to resemble a fingernail. do this with all 4 pieces. reserve the piece u cut out.

now about halfway down the hot dog piece cut very small curved thin strips out the hot dog.. this will be your knuckle.. the top one will look like a a frown the bottom one a smile and then two small small pieces cut out on the middle of those two.. see photo..

place frozen dogs and the nails in microwave on a microwave safe plate and heat until fully cooked. the cuts in the knuckle with heat of microwave will make them start to curl. I do mine for about 1min and 15 seconds... but time may vary depending on wattage of microwave.

let cool so u can handle them.. use pairing knife and spread a bit of ketchup onto where the nail is.. place your reserved nail on top and press into ketchup to hold. do this with all 4 pieces.

now stand up the hot dogs into the ketchup leaning against side of bowl.. now u have bloody severed fingers for lunch! :)
