Zig and Zag are an Irish puppet duo, featured on RTÉ, performed by Ciaran Morrison and Mick O'Hara.

In April 2015, it was announced that the duo would return in 2016 with a 26 episode animated series Zig and Zag commissioned by RTÉ and the BBC.

[6] On 22 September 2020, RTÉ confirmed the return of The Den as a weekend family show reuniting Zig and Zag, Ray D'Arcy and Dustin the Turkey.

Zig was then portrayed as a weak-willed childish simpleton, constantly giggling at rude jokes (like the word "bottom"), obsessed with specific things (such as The Hunt for Red October or his rash) and frequently unaware of what was going on around him.

Cousin Nigel consisted of Zig wearing a pair of drinking glasses over his eyes and a Cub Scouts hat.

They also regularly appear on RTÉ Two in their current incarnations of Podge and Rodge (voiced by O'Hara and Morrison respectively), fellow characters from The Den with an unsavoury past but who are now reformed enough for RTÉ to commission their own primetime chat show, The Podge and Rodge Show.

[11][12] Morrison and O'Hara continue to work in development and as in-demand scriptwriters for a number of companies through their partnership Double Z.

The brothers' decision to work for a UK-based broadcaster caused friction with their former Den colleagues, which led to Dustin later accusing them of 'selling out to the Queen' during a live, heated exchange on 2Phat's 1998 Christmas special.

Among the memorable results was them teaching Wu-Tang Clan's Method Man and Ol' Dirty Bastard "how to fold a serviette like a pineapple".

They starred in a children's programme called Me:Tv for Nickelodeon UK and Ireland in the summer of 2006, the premise of which was kids used their own webcams to present the show.

The series is written by Zig and Zag creators Ciaran Morrison and Mick O'Hara who will also voice the characters.

[17] The first animated series (26 x 11mins) simply entitled Zig and Zag was broadcast on CBBC and RTÉ in Spring 2016.

[18] Zig and Zag made a surprise guest appearance on TFI Friday on 18 December 2015 in what is most likely the last ever live episode of the show.

They joined Chris Evans for the Christmas Special and when Gaby Roslin appeared later in the show she stated that it was the first time all four former Big Breakfast presenters had been together on screen in 21 years.

On the back of their success on The Big Breakfast, the pair were signed by Simon Cowell and released two singles on RCA.
