This question was recently migrated to SU. The original question on SO has 3 answers on it, whereas the migrated question on SU has only 2 answers (screenshots follow the question). Although I can't see any deleted questions on SU, I confirmed with random a mod on SU that there are no other answers on the question.
Why did the answer by Psy not get migrated to SU?
