ON THE SET!

LEFT TO THEIR OWN DEVICES

Between takes, Cory Monteith (Finn), Mark Salling (Puck) and Dianna Agron (Quinn) go hi-tech. Says co-creator Brad Falchuk: "They're always trading iPhone apps and taking really goofy pictures of each other."

SMOOTH MOVES

Lea Michele (Rachel) dances on-camera with Harry Shum Jr. (Mike). Who's the slowest at learning choreography? Salling jokes, "Take the first two syllables of that word and figure it out!" (Sorry, Cory.)

TAKING CHARGE

Jane Lynch's cheerleading coach Sue Sylvester is Glee's queen of mean, but on-set only one thing riles her up: "We had this wonderful thing for a while called Fit Food. It was all organic and tasty. But it cost too much, so they took it away!"

PUCK-ER UP

Salling (kissing up to Kevin McHale, who plays Artie) is all swagger as Puck, but really "he's a pussycat," says Falchuk. "He's always sweet and humble."

CAMERA READY

Matthew Morrison (Will) talks with cinematographer Chris Baffa (left). Says Falchuk: "They're getting savvy with 'Where's the light? Where should I be standing?'"

TWO GOOD

Heather Morris (left, Brittany) and Naya Rivera (Santana) "are always in a two-shot," says Falchuk. "They are just funnier together."

GETTING MOBBED

Amber Riley (Mercedes) and Chris Colfer (Kurt) love playing the party game Mafia on-set. "Amber is good at it," Colfer says. "She will fight you! I just laugh uncontrollably."
