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.

Dave hit us up with a little know curse word in 'Hey Jude' which connects to Father Ted and has some rather interesting bits of info on the extreme measures Dave Grohl's first band went to when he left them, ZZ Top turning down $1 million and some 'Jizz' music (it's not what you think).

Prepare to be amazed.
