In Series 13, the duo teamed up with co-presenter Stephen Mulhern to audition in disguise under the name Disco Dogs, for which they received four 'yesses' from the Judges. In Series 8, the pair each got a brief chance to be a judge, as Simon Cowell was not present for part of the auditions. Whilst the duo's main role in the program is presenting, they have often been called onto the stage to be an interactive part of acts such as magic or danger acts.
Another show the duo do (with the exception of Series 18 in which Dec was joined by Holly Willoughby) is I'm a Celebrity.Get Me Out of Here! which has so far ran for 22 Series.
One being Ant & Dec's Saturday Night Takeaway which has so far ran for 18 seasons with the 100th episode airing on the 3rd March 2018. Despite hosting Britain's Got Talent, they also host the spin-off Britain's Got Talent: The Champions. Ant & Dec also host two other shows that regularly air on ITV.
