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!

On this morning's show Dave revealed why we look like vampires in some of our snaps, how being forgetful and into dark humour means you're actually quite intelligent, explains what an ambivert is, and told us a bizarre story about the option French prisoners used to have in order to skip jail time.
