Slice eggs in half, lengthwise. Scoop out the yolks into a bowl and mix in mayonnaise (not too much!), dry mustard, and celery. Flip the eggwhites over and trim a flat sliver off the rounded side with a paring knife (this will keep them from tipping over and spilling out the filling). Flip the eggwhites hollow-side up again and spoon the filling back into the whites. Sprinkle the eggs with paprika (for that deviled look !).
