Born in Blackburn and raised in Southport, Lee Mack started in comedy after a series of casual jobs, including stableboy and working in a bingo hall. His first taste of stand-up came as a Pontin's bluecoat.
His first experience of the wider circuit came in 1994, when he did his first open mike slot while a student at Brunel University, West London. Within 18 months, he had won the 'So You Think You're Funny' new act competition at the 1995 Edinburgh Fringe and become a full-time comedian.
