Oh man, I'm sitting here with my QI-book of general ignorance, and this topic.. I'm in heaven ^^
For example, did you know that the moon smells of gunpowder?
That Celts have never lived in the UK, but somewhere along the Danube?
That, in Fleming's books, James Bond has a drink every seven pages and that his favourite is tripple whisky?
That Roman emperors ordered the death of a gladiotor with a thumbs up? ( Freedom was a closed fist)
That kilts, bagpipes, haggis, porridge, whisky and tartan are respectively Irish (the word Kilt is Danish), from central asia, Greek, Scandinavian or central european, chinese, and a 18th century myth? They did however invent, among other things, adhesive stamps, bycicle pedals, chloroform, the Encyclopedia Britannica, the lawnmower, marmalade, the raincoat, the speedometer, tarmac, universal standard time and vacuum flasks. (that one was for the scots here)
That five people died in the Great Fire of London? And Samuel Pepys buried a large parmezan cheese in his backyard on the first evening.
And that Columbus thought th Earth was pear-shaped (ever since the ancien Greeks every simple farmer could tell you the Earth was round)
So, that was it for now. And yeah, I loooooove QI ^^
