The 3rd time in the series that Don't Stop Believin' is sang. This time Rachel (Lea Michele) sings the whole song with Mercedes (Amber Riley), Kurt (Chris Colfer), Tina (Jenna Ushkowitz), Finn (Cory Monteith) and Artie (Kevin McHale) singing background. The group re-creates the first time they sang it on stage with the red tops and jeans.
Second time Brittany guesses sweaters to be the glee theme of the week and be wrong.
Although Mr. Schue is never seen wearing glasses in the entire series, he has a pair as a prop and tucks them atop his head after yelling at Unique, Sam, and Blaine in the choir room.
The song "You Have More Friends Than You Know" by Jeff Marx and Mervyn Warren was commissioned by Hancher at the University of Iowa for the "It Gets Better" stage show, a touring stage production which premiered at the University of Iowa in 2013 with a portion of the proceeds to benefit "The Trevor Project".
