Stephen Mulhern made a surprise appearance on the ITV reality show The Neighbourhood on Thursday night, but one contestant had no idea who the presenter was.
During the episode, host Graham Norton informed the teams they would be watching television together. Stephen Mulhern then appeared on screen to introduce a game of Catchphrase, a show he hosts. However, Kevin from the Uni Boys confessed in a cutaway: 'I have no idea who this is, is it Ant or Dec? I think it's one of the two.'
Despite the confusion, the teams played the game, with The Pescuds and The Khans emerging as winners. They earned the right to influence the immunity challenge, selecting the Uni Boys and Lozman-Sturrocks to receive a three-minute delayed start.
The challenge involved teams racing around the neighbourhood while tethered together to assemble a shed. The fastest team would win immunity from the next vote.
