I've noticed that once you leave London you do kind of become a bit more famous. People in London are a bit too cool for school. It's not so unusual to see someone from London in the street. But outside of London people are a bit more excited to see you and come out and support you.

In this quote, David Walliams reflects on the differences in how he is perceived in London versus outside of it. He suggests that in London, people are less likely to be excited or impressed by celebrities, as the city is home to a wide variety of famous individuals, making it a more blasé environment. The phrase "too cool for school" implies that people in London may be more reserved or indifferent to fame, as they are used to seeing public figures regularly and don’t give much attention to them.

Walliams contrasts this with how people react when he is outside of London. He observes that in other places, people are more enthusiastic and supportive when they see a celebrity. This suggests that in less media-saturated areas, the novelty of encountering a well-known figure is still fresh, leading to more genuine excitement and interaction from the public. It emphasizes how people in smaller towns or cities might show more appreciation and admiration for celebrities compared to those in major urban centers like London.

The origin of the quote can be traced to Walliams' career as a comedian, actor, and author. Known for his work on the sketch comedy show Little Britain and his bestselling children's books, Walliams has had significant public exposure in the UK. His comment reflects his experiences navigating public attention in a country where certain areas are more attuned to celebrity culture than others.

Ultimately, Walliams' words highlight how the perception of fame and celebrity can vary depending on the location. His comparison of reactions in London and outside the city serves as a reminder that the novelty of fame can lead to more enthusiastic support in places less accustomed to it, while cities like London, with their high concentration of public figures, tend to be more nonchalant about such encounters.
