Peel the hard boiled eggs and slice them in half lengthwise.
Remove the yolks from the eggs and put them into a medium bowl.
Mash the egg yolks and get as many clumps out as possible.
Add the mayonnaise, mustard, lemon juice, paprika, and salt to taste to the bowl with the egg yolks.
Stir and continue mashing until smooth.
Pipe the egg mixture into the center of the hard boiled egg whites.
(optional) To complete the pumpkin look, cut the tips of the ends off of the gherkins, and place them onto the eggs to form the stem of the “pumpkin”.
