Sleek Geeks is an Australian science television series, hosted by Dr Karl Kruszelnicki and Adam Spencer. The fourteen-part series aired from 3 January 2008, and was based on Kruszelnicki and Spencer's Sleek Geek Week travelling roadshow, as well as Kruszelnicki's Great Moments in Science broadcasts on Triple J radio. The show was co-hosted by fellow "geeks" Yumi Stynes, Ruben Meerman and Dr Stephen Bosi. The program aimed to demonstrate scientific principles and debunk common myths and fallacies, although Kruszelnicki and Spencer were disparaging of similar programs such as Discovery Channel's MythBusters and Sky One's Brainiac: Science Abuse. Sleek Geeks was one of the first batch of television programs offered for sale in Australia on the iTunes Store. Sleek Geeks Season 2 aired from 11 November until 30 December 2010, on ABC1 on a Thursday night at 8.00 pm.
