Molly Shannon makes her Glee debut as Brenda Castle, science teacher, badminton coach and alcoholic extraordinaire. She’s the one person who isn’t afraid to put Sue Sylvester in her place. The video below is a quick behind-the-scenes look of Molly on Glee. Not much is revealed, but it will be interesting to see Sue shake in her shoes for once!

What do you think? Are you excited to see Molly on Glee?

ICE ICE BABY.

I hope this sneak peek airs in Canada too!

TOMORROW.

As part of Gleek Week, various Glee characters have been introducing other Fox shows. Earlier this week we were treated to Mr. Schuester and Finn introducing American Idol. Today, we have Sue and Schue introducing 24. Sue squeezes in a surprising number of Schue-directed insults for a 20 second commercial!

Less than a week until Glee comes back!
