Regardless, the performance led to interest from bookers, and Smith began a new incarnation as a professional comedian in October 2008. Since then, he has performed at the prestigious Tartan Ribbon event at the Edinburgh Festival, debuted his own one-man show "Unfamous", which sold out its run at both the Pleasance Theatre, Edinburgh, and London's Soho Theatre. He also gave a one-off performance of Unfamous at the Elgar rooms in the Royal Albert Hall in March 2011. In April 2011, Smith was invited to take the show to the Melbourne International Festival for one month.
