Is why I love Glee.

Kurt Hummel mentioned the FSM.  While yes, that was just one small portion of the episode, it just made it more awesome.  I am so happy the Beatles, REM, Joan Osborne, and Simon & Garfunkel were licensed for this episode.

Sammy, I've missed you.  Please, you and Dean need to appear on my television far more often. 
Oh, and Katherine Isabelle, is the awesome.
