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.

Today was all about film facts; where Chris Pratt decided to become a real-life hero, Sean Bean went to great heights for his role in Lord of the Rings, Will Smith wanted a new best friend, George Lucas uses 'the force' and how Leonardo DiCaprio really got stuck into The Revenant. 

Everyday's a school day lads.
