The necklace didn't bother me all too much, except when it was dangling from her mouth...a little overkill there. Many routines over the years have featured much more obtrusive props - i.e. Twitch and Katee's door, Twitchington's bed (hhmmmm - think they were covering his lack of overall talent?!).
Anyhoo...overall though, for me it was one of the most memorable routines so far this season and honestly in quite awhile.
