A contestant on today's episode of The Chase underwent a transformation following a conversation with Bradley Walsh.
The 61-year-old host welcomed four new quizzers on Monday's episode of the popular ITV gameshow.
Derek, Holly, Sandy and Dianne tested their wits against Mark Labbett in a bid to win a cash prize.

Derek was up in seat 1 and the former HR manager from Halifax said he'd spend any money won on today's show on a holiday to the USA.
The 70-year-old added: "I'd really like to go way out west and ride horseback through those magnificent valleys and canyons."
Bradley pointed out the similarities of Derek's travel dream with the 1991 film City Slickers - and asked what he'd refer to himself as if he were a cowboy.
Derek shot back: "Dirk. Similar to Derek isn't it?"
Bradley was in hysterics at the comments - and proceeded to refer to him by his new name for the rest of the show.
The host was in stitches when the production team changed his name from Derek to Dirk on the podium.
He said: "I love the fact that we're calling him Dirk. I think that's fantastic."
Viewers following the show on Twitter were also thrilled by the name change on Monday's episode.
Victoria said: "They’ve changed his name to Dirk only just noticed when Brad pointed it out."
Robin added: "Nice one techie bods - Derek to Dirk"
Steve commented, alongside laughing emojis: "You can do it Dirk just get back"
Derek proceeded to build up £2,000 in his cash-builder before avoiding Mark Labbett to book his place in the Final Chase.
He was competing alongside Sandy and Dianne in the final Chase for a combined total of £14,000.
The team built up 17 steps in the last round, but were caught by The Beast with 13 seconds remaining.
The Chase airs weekdays at 5pm on ITV and ITV Hub
