What exactly is 'red nose day' ?

You know, this is a really good question (that we usually remember to answer in our first Red Nose Day post of the year) so thanks for asking it!

It’s a fundraiser and live telethon put on by Comic Relief. via the FAQ:

Red Nose Day is a UK-wide fundraising event organised by Comic Relief every two years. On Red Nose Day everyone, including celebrities, is encouraged to cast inhibitions aside, put on a Red Nose and do something funny for money.

It culminates in a night of cutting-edge comedy and moving documentary films on BBC One. Red Nose Day unites the entire nation in trying to make a difference to the lives of countless people across Africa and the UK who are facing terrible injustice or living in desperate poverty.

Sometimes The Doctor makes an appearance in a sketch. Two of our favorites from past years have been the Eleventh Doctor, Amy, and Rory in Time Part 1 & Part 2 (2011) and David Tennant and Catherine Tate’s turn in 2007.

We should have video of their 2013 appearances up soon.
