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!

He had us baffled this morning as to what food is literally like a drug. I'll give you a hint - he's an expert of this topic!?

Dermot was baffled too, by his own story, as his fact sounds a touch fictional. 

There's also a gripping stat about smartphone usage and how a Chinese province is tackling jaywalkers.
