Surprise adult trick-or-treaters with wonderfully wicked sweets. Combine one 6-ounce box orange-flavored JELL-O® and 2 cups boiling water. Stir until dissolved, then cool; add 2 cups Smirnoff® orange-flavored vodka. Pour into shot glasses and refrigerate until set. Serve on a silver party tray embellished with glittery little pumpkins, and cap each with a dollop of whipped topping and Halloween sprinkles.
