The opening to this episode was Sue Sylvester venturing into cartoonish villainy (as opposed to cartoonish supervillainy, of course). Total awesome and I loved every bit of Principal Sue Sylvester, especially her war on junk food.
Gwyneth Paltrow fits in perfectly on this show. I wouldn't mind seeing her turn up more often. Although, I won't lie, her rendition of Cee-Lo's "Fuck You" made me pine for the original. (Won't you click the link and support The W?)
The cuts to the kids getting shot down by Will in favor of Journey songs were hilarious.
Music choices didn't do it for me this week. They can't all be gems, I guess.
In the list, you did not include "Ma Hunkel" the original Red Tornado (also grandmother of Cyclone) At various points, Alan Scott has taken off the ring and given up being Green Lantern only to put the ring back on later.
