My reaction to this has changed over the past week. First I thought it was lame and silly. Then it got stuck in my head one night and kept me up, and I hated it and NancyLebovitz. Then it continued to be stuck in my head off and on, and Stockholm Syndrome or something must have kicked in because now I like it and think it's amusing.
Something similar happened to me, but over a period of many months.
and get nothing!
Seriously, this strikes me and a lot of people as pretty funny, but isn't much like the typical joke.
Edited to add: Poll and discussion. Short version: being amused by the song is rarer than I would have thought, though the LW consensus may be usually strong.
