These are both embarrassingly easy. A few well placed knife cuts make the knuckles and 1 removal of the fingernail. Drop them in boiling water to heat and the water will magnify the slashed finger and fingernail for you. Serve with plenty of ketchup!
As for the Dirt Cake, make according to the box and let cool. Light layer of frosting, top with ground Oreos and gummy worms. Gross, fun, effective~!
