The Substitute
I greatly enjoyed this episode. Gwyneth Paltrow was great. I hope see her again. An episode with both her and NPH would be just about the best thing ever.
Will's hallucination that the glee kids were little was hilarious. Also loved when some of the kids pretended to be each other when Holly first came in. Puck pretending to be Finn was funny, but Brittany saying "I'm Mike Chang" with a deep voice made me lose it. The buttered floor was great as well. It was funny when Rachel fell, but Kurt falling was even funnier. Oh, and Kurt and Blaine talking and Mercedes only hearing "Gay, gay, gay..." was great. Also loved the purse falling out of Kurt's mouth. And finally, Will's obsession with finding a Journey song they hadn't done yet.
Loved their version of Forget You. Also, I've never seen Singing in the Rain, so I was fine with the Glee versions. I love Matthew Morrison's voice, so it's all good.
