2 things I noticed again after watching the eppy again
1) the Toxic dance routine was a tribute to Bob Fosse ala All That Jazz, if you are not familiar with him, go view Paula Abdul's Cold Hearted video....
2) Rachele Brooke Smith...she starred in Center Stage: Turn it up and Bring It On: Fight to the Finish, was a back up dancer in the eppy....
Just in case you don't recall what she looks like..
Also, I totally see a duet/battle between Mr. Shue and Carl...
