Dr. Mitzi encourages you to get your fun on and not take yourself too seriously.  In this video she also mentions Red Nose Day. 

The following information,  courtesy of  Rednoseday.com and Wikipedia gives more background about Red Nose Day and Comic Relief, UK.

Red Nose Day is a UK-wide fundraising event organized by Comic Relief every two years. On Red Nose Day everyone is encouraged to cast inhibitions aside, put on a Red Nose and do something a little bit silly to raise money – celebrities included! It culminates in a night of extraordinary comedy and moving documentary films on BBC 1. Red Nose Day is an event that unites the entire nation in making a  difference to the lives of thousands of people, both across Africa and in the UK, — those facing terrible injustice or living in abject poverty.

Comic Relief, which organizes Red Nose Day is a British charity organization, founded in 1985 by comedy scriptwriter Richard Curtis and Alexander Mendis in response to devastating famine in Ethiopia. Comic Relief was launched live on Noel Edmond’s Late, Late Breakfast Show on BBC1 on Christmas Day 1985 from a refugee camp in Sudan.  Noted charity worker, Jane Tewson, came up with the idea for Comic Relief and she established it as the operating name of Charity Projects, a registered charity in England and Scotland.  

 The highlight of Comic Relief’s appeal is an annual telethon held in March, alternating as Red Nose Day. Comic Relief is one of the two high profile telethon events held in Britain, the other being Children in Need held annually in November.

 One of the fundamental principles behind working at Comic Relief is the "Golden Pound Principle" where every single pound (currency) donated is spent on charitable projects. All operating costs such such as staff salaries are covered by corporate sponsors, or interest which is earned while money raised is waiting to be spent (granted) to charitable projects.

Currently, its two main supporters are the BBC, and Sainsbury’s supermarket. The BBC is responsible for the live television extravaganza on Red Nose Day, and Sainsbury’s sells merchandise on behalf of the charity.

In 2002, Comic Relief and BBC Sport  teamed up to create Sport Relief, a new initiative, aiming to unite the sporting community and culminate in a night of sport, entertainment and fundraising on BBC1. Sport Relief is a biennial charity event, and the campaign deliberately alternates years with Red Nose Day, Comic Relief’s flagship event. Comic Relief occurs in odd-numbered years, and Sport Relief in even numbered years.
