In 2008, Scott became the UK organiser of International Talk Like a Pirate Day, and was subsequently nominated by his friends to run for presidency of the University of York Students' Union as "Mad Cap'n Tom Scott". Despite running as a joke, he won the election and served as the organisation's 48th president. That same year, Scott and three friends formed the comedy troupe, The Technical Difficulties, with whom he hosted an eponymous radio show on University Radio York. The show later won the Kevin Greening award at the Student Radio Awards.
