In this week's behind the scenes Glee installment, Harry Shum Jr. (Mike) is giving you a full tour of the set. Are the lockers real? Where's the auditorium really located? And what sorta naughty pamphlets does Emma have in her office? Plus, the guys give you the inside scoop on what it was like to film their rocked-out version of "The Rain in Spain." Plus, Samuel Larsen (Joe) talks about those infamous dredlocks of his! And Chord Overstreet (Sam) is adorably (fake) confused.
