It's Easter. I survived the annual maelstrom most call Easter Dinner. It had me thinking about the Fallout world and how the people of that universe celebrate Easter. Decorate Easter Grenades, mayhap. I have images of perhaps a Super Mutant or Raider with bunny ears. 200 year old Peeps [those little disgusting marshmallow ducks/birds]...probably called Zeeps, or something.
For the more morbid side of things, perhaps a Brotherhood of Steel Paladin nailed to a cross, via railway spikes. I could see it.
