Planes, trains and automobiles… it’s Josh’s time to shine with our topic of the week; ‘Transport’. He’s an avid fan of anything with an engine. Grace wanted him to teach her everything - from the reasons behind why people trainspot, to whether we’ll ever have flying cars one day.

Later the pair are joined by Oliver Wood who quizzes them on the London Underground. Josh should breeze through this week’s trivia. Emphasis on should.
