David Walliams is hosting a 24-hour online panel show this weekend in order to raise funds for Red Nose Day and Comic Relief. Starting at 12pm Saturday 5 March and running until, obviously, 12pm Sunday 6 March, 24 Hour Panel People will be exclusively streamed live in its entirety on the BBC's Red Nose Day web page.
It is the first time that the BBC is doing something of this scale and duration, and hopes that it will raise massive amounts of cash for worthy causes both in the UK and Africa.
Twitter users are also encouraged to spread the word using the #24pp hashtag, which has already been flooding the social networking service for the last few days.
While the running times are yet to be confirmed, the content of the online video-a-thon will include a version of The Generation Game hosted by Vernon Kay, with Walliams and his mum battling it out against comedian Miranda Hart and her on screen mother, actress Patricia Hodge. Plus, there will be special versions of Blankety Blank, They Think it's All Over, Through the Keyhole, Never Mind the Buzzcocks, and, perhaps most excitingly, a reuniting of Una Stubbs and Lionel Blair for Give us a Clue.
There'll be plenty more too, and all of them will feature David Walliams.
Highlights packages will be shown on BBC Three and BBC One (and HD) on Red Nose night on 11 March, but this weekend will be the only time you can see everything.
So, get your wallets out, and some matchsticks for your eyelids, and enjoy the action at www.bbc.co.uk/rednoseday/24hourpanelpeople/.
