Answer by taking a quote from the following article:

Anthony McPartlin, OBE (born 18 November 1975) and Declan Donnelly, OBE (born 25 September 1975), known collectively as Ant & Dec, are an English comedy TV presenting, television producing, acting and former music duo from Newcastle upon Tyne, England. The duo met as actors on the children's television show Byker Grove, during which and in their subsequent pop career they were respectively known as PJ & Duncan - the names of the characters they played on the show. They have had a successful career as television presenters, presenting shows such as SMTV Live, CD:UK, Friends

Ant & Dec got their first presenting job in 1994, while they were still releasing music under the alias of PJ & Duncan. They co-presented a Saturday-morning children's show entitled Gimme 5, which was broadcast on CITV. The show only lasted two series before being dropped from the airwaves. In 1995, the duo were once again offered a job on CBBC, this time presenting their own series, entitled The Ant & Dec Show. The series was broadcast from 1995 to 1997, and in 1996, Ant & Dec won two BAFTA Awards, one for 'Best Children's Show' and one for 'Best Sketch Comedy Show'. In 1997, a VHS release, entitled The Ant & Dec Show - Confidential, was made available in shops, and featured an hour of the best bits from three years of the programme, as well as specially recorded sketches and music videos.  In 1998, the duo switched to Channel 4, presenting an early-evening children's show entitled Ant & Dec Unzipped. This show also won a BAFTA, but was dropped from the airwaves after just one series. ITV soon signed the duo in August 1998, and within weeks, were assigned to present ITV1's Saturday morning programmes SMTV Live and CD:UK, alongside old friend Cat Deeley. The duo presented the shows alongside Deeley for three years, becoming the most popular ITV Saturday morning show. The programme's success was the mix of games such as Eat My Goal, Wonkey Donkey and Challenge Ant, sketches such as "Dec Says" and the "Secret of My Success", and the chemistry between Ant, Dec and Cat. Two SMTV VHS releases, compiling the best bits from both shows, were released in 2000 and 2001 respectively. Ant & Dec also starred in the children's TV series Engie Benjy during their time on SMTV.  Ant & Dec made their permanent departure from children's television in 2001 after trying out formats like Friends Like These for BBC One in 2000 and Slap Bang with Ant & Dec for ITV in 2001 (which was basically SMTV in the evening even playing Challenge Ant against adults). They have since said that the main reason they left SMTV was because the Pop Idol live finals were due to begin on Saturday nights on ITV in December 2001.

What was the name of the childrens show?
