Rob Beckett invites guests Melvin Odoom, Ahir Shah, Josh Jones and Harriet Kemsley 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, they are asked to work out the second half of some truly mind-blowing facts and decipher Facts from Fibs (Do cows moo with regional accents? Did Einstein genuinely work at Oktoberfest?) as well as throwing some of their own trivia out there in the hope of getting more points.

We find out whether honeybees can be trained to sniff out landmines, Melvin shocks everyone with his revelation about using
dial-up internet, and Ahir confesses to being a trainspotter and reveals the ingenious method Google uses to cut grass. And did Rob accidentally join a gang?

As they tackle the final quickfire round, who will end up with the most trivia on Rob's Wall of Facts, and which team will be the undeniable winners?
