Red Nose day is part of the Comic Relief.
"Comic Relief was set up by comedians and uses comedy and laughter to get serious messages across, while making sure that everyone who gets involved can have fun at the same time. Over the years, more than 2 thousand celebrities have given their time and talent to Comic Relief, from Lenny Henry, Billy Connolly, John Cleese and Jerry Springer to Johnny Depp, Ali G, Davina McCall, Robbie Williams, Steve Coogan, Paul Whitehouse, Whoopi Goldberg and Woody Allen"
"Red Nose Day is a UK-wide fundraising event organised by Comic Relief every 2 years which culminates in a night of extraordinary comedy and moving documentary films. It's the biggest TV fundraising event in the UK calendar. On Red Nose Day everyone in England, Scotland, Wales and Northern Ireland is encouraged to cast inhibitions aside, put on a Red Nose, and do something a bit silly to raise money - celebrities included. It is an event that unites the entire nation in trying to make a difference to the lives of thousands of individuals facing terrible injustice or living in abject poverty"
