Jane Lynch, the epitome of the ensemble actress, topped off her opening monologue on Saturday Night Live with a song that jokingly claimed her character, cheerleading coach Sue Sylvester, was the only reason to watch Glee.

Lynch, who's also starred in SNL alum Christopher Guest's ensemble mockumentaries, sang what she maintained should be the Fox series' theme song — co-written by two bottles of Jose Cuervo.

The show kept its focus on Glee in the night's first full sketch, as Lynch played Sylvester, who introduces Kristen Wiig's troublemaking character Gilly as a new student. The skit mostly poked fun atGlee's characters, highlighting the often one-note use of Mercedes (Keenan Thompson), Artie (Fred Armisen), Kurt (Andy Samberg) and Mr. Schuester (Jason Sudeikis).
