When Dave's World starts off with Dave saying, "I am a Spermologist", you know you're in for a treat.

We were baffled by the word, but it made complete sense when he revealed that a Spermologist is a term used for someone who collects trivia. No semen involved thank God!

The Spermologist (I can't stop saying it now) lived up to his title as he told us the history behind the phrase 'ham actor', had a stinky fact from movie The Usual Suspects, deciphered some Hebrew and shocked us with some info about a surgeon who's botched surgery ended up with three people dying. 

We don't know where he gets it all from but we love the way he feeds our brains.
