Next week on Thursday (Dec. 5) 'Glee' will air it's fall finale, a holiday-themed episode entitled 'Previously Unaired Christmas.'

The episode will be introduced by Sue Sylvester (Jane Lynch), who claims it was so offensive that FOX didn't allow it to air last year. The New Directions will spend their time auditioning for the McKinley nativity scene while the New York crew work as elves.

As expected, the season five, episode eight episode will be full of Christmas songs (and one by the Supremes).

You can watch the promo above.
