We all have that one friend who just loves to drop random facts into conversations, just to prove they know stuff. For Dermot, Dave is that friend!

If you’ve ever wondered why airports are laid out the way they are, what you can do at the speed of sound, or what colour eyes you’re best off having, then Dave’s World is the place for you!

This morning, Dave thinks he has discovered the world's best invention - but his name for it is a little bit suss. He also teaches us a couple of crazy laws from Canada and China. Mad stuff altogether!!
