Rob Beckett's Undeniable

Rob Beckett invites guests Tom Allen, Joanne McNally, Aaron Simmonds and Michael Odewale to bring as many brilliant facts as they can in an attempt to impress everyone and hopefully get on Rob's closely guarded Wall of Facts.

Teamed up in pairs, the guests are asked to decipher Facts from Fibs (Did Romans really have 'Vomitoriums' to throw up in? Can fish deafen dolphins by having loud sex?) as well as throwing some of their own trivia out there in the hope of getting more points.

Tom Allen surprises everyone with the fact that he's never had a cup of tea in his life. Viewers learn about an extremely bizarre use of Tina Turner's music, and why Rob thinks Joanne is a God thief! Aaron divulges his deep love of Harry Potter.

Viewers find out whether it's illegal or not to wear skinny jeans in North Korea. Tom Allen bombards everyone with facts about musicals.

Both teams take on the final quickfire round to find out who will end up with the most on Rob's Wall of Facts, and who will be crowned this week's undeniable winners.
