It's 30 years since CBBC started airing short links between shows. To celebrate, Hacker has brought together the finest presenters, past, present and even a new one, to reminisce and laugh at a few bloopers.

Two teams fight it out to dodge detention, and put the cool back into school, in a mischievous mix of tongue-in-cheek comedy, off-the-wall questions, nonsensical studio games and slapstick challenges.

Hacker Time is a British children's television show on CBBC starring Hacker T. Dog with one or more famous celebrities such as Anton du Beke and Dani Harmer. The show follows the same theme of Hacker tricking the celebrity/s into his studio, interviewing them, and then watching sketches and outtakes from other programmes. Each episode is approximately 30 minutes long. The theme song and ending songs are sung by Phil Fletcher who is Hacker T. Dog's puppeteer and voice actor. The show first aired in September 2011 and was rated #10 in the Weekly Top 10 Programmes for the week of 3–9 October 2011. The second series of Hacker Time began airing on 6 August 2012 and instead of the guests being tricked onto the show, Hacker sends out Wilf and Herman to kidnap them and get them to come onto the show. The third series of the show started on 22 July 2013 where Derek books better guests than Hacker has in mind.
