The story seems to be one of silliness, rather than anything else. At a pumpkin carving party for holloween the latecomer didn't have any ideas, they decided on the symbol in order to "stick it to Hltler", which made an appearance as a shot in the head pumpkin. The two people involved I had never met before, though they were some of the friendliest, as well as a strangest, people I had ever met.
