Thank you so much for that comment!  My thoughts exactly, and I felt so bad for tge two "actual" dancers.  I'd be so pissed if I had to share the stage with a fat shit who fucked up the choreography and couldn't pull off the dance moves.  Those two ladies were mostly in synch and were totally nailing it.  They rehearsed, they knew the dance, they have put forth the effort, and it shows.
