Episode 5 of Totally Bonkers Guinness World Records, the programme that brings together the weird and wonderful world of record-breaking goes out at 8pm on ITV2 tonight.

The show features some of the most entertaining Guinness World Records and the brilliant characters who set them.

This week's incredible collection of record holders includes Francisco Domingo Joaquim who has the world's widest mouth, a group of German musical instruments makers who have constructed the world's largest violin, and Julia, whose talent is opening beer bottles with her feet!
