Follow the directions on the back of the pudding box (or in the link for the homemade pudding) and set aside.
Take two rows of Oreos and pull apart the Oreos, scrape off the cream on one side of the Oreos and add the bare cookies into a ziplock bag.
Take a rolling pin and crush the Oreos.
Grab a parfait cup and fill the cup 3/4 of the way with the pudding.
Top with the crushed Oreos and place in a few worms.
