X user @OxKruzr is, for this Halloween, dressing as the most famous character created by Stan Kelly of the satirical newspaper The Onion. Note the right side of this cartoon:
Kelly's 2015 comic about a future with legalized drugs imagines degenerates labeled as "sickos" enjoying the downfall of society while cackling "Yes...ha ha ha...yes." It's become a meme. We Sicko-Americans try to take it in stride as a joke from a less culturally sensitive time.
