There's a lot going on -- the Troubletones are gaining strength in numbers, and New Directions has decided to launch a mash-up competition. Meanwhile, Puck's making moves on his crush, Shelby; Sue is going full force with her congressional bid; and Rachel and Kurt are working things out.
As for the music, Puck appropriately covers Van Halen's 'Hot For Teacher,' while the rest of the students go for impressive mash-ups. Mercedes and Santana perform an epic mix of Adele's 'Rumour Has It' and 'Someone Like You,' and New Directions take on Hall & Oates' 'I Can't Go for That' along with their 'You Make My Dreams.'
Mr. Schue and Ms. Corcoran get in on the action with Lady Gaga's 'You and I' and Eddie Rabbitt and Crystal Gayle's song of the same name, while New Directions and the Troubletones go to battle with a mash-up of Pat Benatar's 'Hit Me with Your Best Shot' and Blondie's 'One Way or Another.'
