Catherine Tate's Nan (simply referred to as Nan on-screen) is a BBC One spin-off series of specials which follows the character of Joanie Taylor (Catherine Tate) from the original sketch comedy series The Catherine Tate Show.

In a spoof to Charles Dickens' A Christmas Carol, Nan Taylor becomes a real scrooge and loses her Christmas spirit.

After turning away her family members, the Cratchits, this causes Jamie to snap and walk out.

Note: Viewing figures for the three specials between 2014 and 2015 were not available from BARB's website, as they were below the top 30 programmes of those weeks.

Nan's Christmas Carol (as 'The Catherine Tate Show: Nan's Xmas Carol') was released on Region 2 DVD in the United Kingdom via 2 Entertain on 29 November 2010.
