GLEE (8:00-9:01 PM ET/PT) – “Blame It on the Alcohol”
Principal Figgins (guest star Iqbal Theba) teaches the student body about the danger of underage drinking, and the glee club is personally touched by the message. Meanwhile, Mr. Schuester (Matthew Morrison) and Coach Beiste (guest star Dot-Marie Jones) indulge in a little fun of their own.
