Finn and Quinn ask Emma for advice on how to be cool again. Emma accidentally suggests sunglasses, but ultimately tells them to be themselves.
Will does a solo version of “The Thong Song” with Emma while she is wearing her wedding dress. He ends up slipping on her train and pulling her on top of him. Ken sees this and looks pissed.

Puck and Rachel are working on a song at her place. During a break they start making out. It turns out Puck’s mother made him feel guilty about not finding a good Jewish girl and he went after Rachel.
