Mad//Fest London is the “UK’s biggest, boldest and most distinctive marketing/advertising festival”, which launched in 2018.

In 2024 they had grown to 12,000 attendees and the 2025 Festival is running from July 1^st to 3^rd.

Richard Ayoade is headlining on the 1^st and Jimmy on the 3^rd.

Jimmy’s speaker session is going to be with Rory Sutherland and the blurb says:

Carr, known for his sharp wit and controversial humour, and Sutherland, a celebrated advertising guru and author famed for his insights into behavioural science, will explore the parallels between crafting a joke and creating a compelling advertising campaign.

“Rory Sutherland is one of my favourite people. In a world of noise, he’s the signal – he’s full of insight, ideas and creativity. And I’m forever being told I’m full of something. Let’s see where the conversation takes us,” said Carr.

“Brands and comedy have this sort of dangerous liaison where there’s excitement, chemistry and jeopardy almost in equal measure. As I’ve got to know Jimmy and what drives his razor-sharp,intelligent and often controversial brand of humour, I’ve been thinking a lot about how brands and comedy can complement each other and perhaps even realise a new golden era of creative advertising,” added Sutherland. 

“Humour is the brain’s emotional reward for thinking differently.”
