Will pushes tables around to make room to dance while Emma walks down the hallway. She's wearing a wedding dress -- and it goes on and on and on, with a train that's longer than the Amtrak local. She enters the room, and explains to Will that the dress belongs to her cousin Betty, who was (along with Emma) obsessed with Princess Di. She's wearing the dress because Betty didn't wear her dress for her pre-wedding dance practice, and as a result her husband stepped on the train, they had a fight at the reception, the priest cried, and the marriage failed after three months. She starts to rethink wearing this cursed wedding dress, but Will tells her it makes sense to see how she'll move in the dress. His plan is to start with Ken's song and then try to work in Emma's choice. And then Will starts singing and dancing to "The Thong Song." And these hardly seem like lessons that she'll be able to use with Ken, mostly because they involve her standing still while Will gyrates around her. And when he tries to bring her into the dance, she trips over the train and falls on top of her. Which is awkward for them, but even more awkward for Ken, who is watching through one of the omnipresent glass walls.
Football practice. The team is huddled, and Finn calls the play. But suddenly there's rebellion. Some members of the team have decided that Finn is not manly enough to be their leader since he joined "Homo Explosion." (Where can I sign up for that?) Finn reminds them that Glee helped them win their first game of the season, but they don't seem to care. One of the players expresses doubt that Finn is man enough to have knocked up Quinn, and wonders whether a real man didn't slip in and do it for him. So Finn tackles him. Ken breaks up the fight and calls the team to the sidelines. As he's berating them, he notices that Puck is missing. Finn explains that Puck had to miss practice for some Glee-related activity. Ken yells at them for not acting enough like a team. And to help build that team spirit, he's adding a new Thursday practice. Finn reminds him that Thursdays is when Glee rehearses, but Ken doesn't care. The new practice is mandatory -- anyone who misses it is off the team. Commercials.
